this has always been a good help to me as well with my beaumontHINGES*The 1968-72 models interchange with one another, so ahardtop/convertible would use the same hinge with the El Camino,sedan, or station wagons, along with the 1969-72 Grand Prix and MonteCarlo.HOOD HINGES1968 Chevelle/El Camino Hood hinges are interchangeable, and thereare two categories: one version built before 11/30/67, and anotherbuilt after 11/30/67. The hinges can be found on the followingvehicles:1968-79 Chevrolet Novas and BOP variants of the X-car1968 Chevrolet full size (Impala, Caprice, Bel Air, Biscayne)If using the hinges from a 1968-72 Pontiac Tempest/LeMans, somemodifications may be needed. If using the hinges on the earlyproduction models (before 11/30/67), the rear bolt slot will have tobe elongated, and the fit and function will not have any adverseeffects.1969 Chevelles only interchange with the 1969 full size Chevrolet,and there have been no other interchangability.These hinges can be used on a 1968 Chevelle if the hood and hingesare salvaged together from a 1969 model, but might not be concourscorrect.One of the clues that distinguishes the hinges and hoods is that the1969 type is dimpled around the rear bolt mount, while 1968s aresmooth and parallel to the front bolt.1970-72 hood hinges will fit onto 1969 Chevelles, but not the otherway around, since the hinges do not have the extended outriggerDOOR HANDLESThe outside door handles have an interchangability with other GMmarques, and the list that applies to the Chevelle can be found onother GM vehicles. The downward angle (mounting area) of the handlesdiffer, so it is necessary to compare the existing handle to anotherto ensure fit and function1968/69 Chevelles, along with 1968-72 El Caminos, interchange withthe following:1968-72 Chevelle Station Wagon1971/72 GMC Sprints (El Caminos that are sold by GMC)1968/69 Buick Skylark/Special (all models and bodystyles)SHEETMETAL1968-72 Chevelle decklids interchange with the following:1970-72 Monte Carlo1970-72 Buick Skylark*The roof panel, which is the sheetmetal part only, interchanges withthe A-body hardtops built by all GM divisions.This means that a Cutlass Supreme (exc. 1970-72 Holiday coupebodystyle), Lemans, and Skylark roof panel would fit on a 1968-72Chevelle (including the 1968/69 300 series post coupe), but it iswise to compare the salvaged piece with the existing panel beforecutting and welding (use a MIG welder).The roof panel does not include the sail panels, and it might be wiseto salvage an entire roof assembly from a hardtop of the same year asthe car that is in need of a roof transplant.The roof panel is spot-welded to the sail panels (the upper part ofthe quarter panel), and the spot welds must be cut when removing theroof panel1968/69 Chevelles (all bodystyles) used the same header panel (andindividual components), but with minor differences (see below).The only difference is that the core support (for both 1968/69) willhave different holes and cutouts to accomodate the A/C condenserlines, as well as the opening for the radiator. Core supports with20 3/8" radiators will have a smaller opening, as opposed to 28 3/8"core supports.There are three script emblems used. 1968 and 1969 Chevelles willhave an emblem that reads "Chevelle", but 1969 Chevelles will havea "BY CHEVROLET" bar beneath the Chevelle script. El Caminos used ascript that read "el Camino", and the Nomad station wagon will have ascript that reads "Chevrolet".The front header panel trim piece is the same for both 1968 and 1969,but 1969s will have two smaller chrome pieces between the headlighttrim buckets.The hood latch and grille brackets are different due to the grilleused for each vehicle. The upper hood hinge seen above is from a1969 Chevelle, and the one on the bottom is from a 1968 Chevelle.1968 models used an aluminum grille, fastened with rivets, while 1969models used a plastic grille, fastened with screws on the front.The front gravel shield, which is known as the bumper filler, isinterchangeable, but there is one clue: 1969 models have a curvedsection for the hood latch lever to clear, and there are provisionsfor the lower grille mounts, which are riveted in place.The aftermarket piece (available from Year One) has two brackets,located underneath, that must be welded in place to attach the gravelshield to the fender.The doorskin panel for 1968/69 Chevelle hardtops/convertibles, eithera full or partial, will interchange, and here's the otherapplications used:4/20/00 update: the 1969 doorskin panel will fit 1968 hardtops withminor mods (I am sure that the doorskin panel will fit 1968-72 ElCaminos, but modifications are needed for proper fitment).HOODS1968/69 hoods*The 1968 and 1969 SS hoods, along with the standard flat hood, donot interchnage, but the hoods can be used on either model if thehinges are used in conjunction with the hood.QUARTERS1969 Chevelle/Beaumont full quarter panels*If using a 1969 Chevelle hardtop replacement quarter panel(available from General Motors) on a 1968 hardtop, then there is apossibility of modifying the lower rear section that surrounds thebumper, in which a 1968 lower patch piece can be grafted if the lowerpanel is modified to fit . The hole for the marker light can bewelded in using a patch of sheetmetal.FENDERS1968/69 Chevelle fenders*1968/69 Chevelle/El Camino fenders are identical in size, but theonly difference is the cutouts for the side markers. (Refer to theFAQ concerning 1968/69 body parts.)BUMPERSThe bumpers, either the front or rear, have limited interchangabliltyVENTGLASS*This piece is commonly interchangeable with all 1968 2-doorhardtops/convertibles, and the vent wing assembly is a directinterchange.Note: 1968 was the only year that the vent assembly was present on ahardtop, before GM used the Astro Ventilation system on 1969 A-bodyhardtops. 1969-72 door glass, for the hardtop/convertible, is a one-piece design.68 2 DOOR HARDTOP GLASS*The vent glass is a one-year item for 1968s, and this also holdstrue for the door glass. The window regulator (which has a crossarmassembly) and its parts are interchangeable with the following:1968-72 El Caminos1968 2-door hardtops/convertibles1968-72 pillared coupes built by the BOP marques.QUARTER GLASSThe quarter glass for 1968/69 Chevelle 2-door hardtops willinterchange, and there is a rumor that the quarter glass from anOldsmobile Cutlass 2-door hardtop will interchange with 1968/69Chevelle hardtops. I have little knowledge for the Buick Skylark; itmight interchange with the Chevelle, but the Chevelle glass (which issmaller) would not fit the Buick. Another note: the hardtop glass,which includes the 1968/69 Chevelle, will interchange with the1968/69 Pontiac Beaumont (Pontiac of Canada), a Canadian builtvariant of the Chevelle with a Pontiac-like grille.WINDSHIELDThe 1968-72 hardtops and convertibles used the same windshieldassembly with one other note:1970-72 windshields incorporate an integrated antenna in thewindshield.REAR GLASSThe 1968-72 Chevelle rear glass for hardtops and pillared coupes willinterchange with the following vehicles:1970-72 Monte Carlo1969-70 Pontiac Grand PrixREVEAL MOULDINGSThe reveal moldings, matched to the body contours, will interchangeif taking the glass (windshield, rear window) and the relatedhardware from a thrashed out A-car.OUTSIDE MIRRORSThere is limited interchange for outside mirrors, in which optionsand mirror styles varied. Each GM division had its own mirror style,with some exceptions. The Chevrolet mirrors are interchangeable, andthere are other models in the Chevrolet marque that wouldinterchange:1968 door mirrors (the round type) are interchangeable with thefollowing:1968 Chevrolet full size exc. Impala hardtop and Custom1968-72 Novas1971/72 Pontiac Ventura IINote: this mirror does not have the bow tie embossed into the chrome.1969-72 outside nonremote mirrors are interchangeable with thefollowing:1973-79 Novas (and BOP variants)RADSRADIATORThe radiator dimensions vary with application, like engine size, andwhich options are available, like HD cooling and A/C.The base radiator (commonly found on six cylinder and non-A/C cars)measured 20 3/4 x 16 1/8 inches, and the HD radiator measures 28 3/8x 16 1/8 inches.The HD radiator is the most preferred, and the cores varied from 2 to4 (sometimes five, typical for those that find radiators from aCadillac) rows.The cooling tank on 1972 models is angled, and this distinguished itfrom the earlier radiators. There is also a provision for a coolantrecovery system, which is the small tube that is located next to theradiator cap.For the dimensions that involve the automatic tranny cooling lines,the earlier spacing measures 12 inches, while 1972 and laterradiators measures at 8 1/2 inches.The dimensions may be a tip when measuring a used radiator salvagedfrom the wrecking yard.Other GM vehicles from the 1970s (1971-76) may use a radiator thatmay fit into a Chevelle or other GM A-body, and this means thatfinding a radiator for an LS6 or GEN VI 502 big block (a four core)could mean looking under the hood of a Cadillac (e.g. a Coupe DeVille) or BOP full size vehicle (LeSabre, Bonneville, Ninety Eight).Another way to locate a radiator is to reference the HollanderInterchange Manual, which has different engine options thatinterchange with what might be needed.Note: Some of the radiators from the BOP/C cars of 1971-76 vintagewill have a fitting on the RH tank for the 3/4" heater hose, which isthe primary hose that flows antifreeze back into the radiator. Mostof the OEM part numbers have been discontinued, and the wrecking yardmight be the logical choice.REAR END HOUSINGS*1968-72 rearend housings measure 58.5 inches from flange to flange,and with the brake drums in place, the total dimensions measure 62.5inches. The dimensions are similar to the 1970-81 Camaro/Firebird,and 1975-79 X-cars and clones, except leaf springs were used.Note: internal components have a characteristic that is common to thehousing used: 10 bolt pieces fit other 8.125" 10-bolt housings (therearend used in Chevrolets), and 12-bolt pieces interchange withother 12-bolt housings (not the one from the Chevrolet pickup orOldsmobile, which has a 12 bolt cover and a 10 bolt gear, whichmeasures 8.3"). This means that a posi carrier will retrofit in placeof a standard differential.Axle shafts are common to the housing used, and due to the usualcharacteristics like overall length and spline count, the shafts onlyinterchange with the housing that is used. (e.g. 12 bolt shafts fitother 12-bolts, and 10 bolt shafts fit other 10-bolts.)REAR TRAILING ARMSThe rear trailing arms (or control arms) consist of four arms thatconnect the rearend to the frame, and the setup consists of two longand two short arms. The lower trailing arms for use with a sway baris unique, and the usual characteristics is that the arm is boxed andgussetted. The upper arms vary, and there are two part numbers in theChevrolet Parts Interchange Manual that separate 1964-67 and 1968-72Chevelles and BOP A-Bodies.The lower arms are interchangeable (allyears), and a car that did not have a sway bar can be modified tofit.CONTROL ARMSMost of the control arms for the 1964-72 Chevelle interchangeFRONT SPRINGSThe springs vary with application and chassis packages, but there isone thing that is important: 1968-72 A-cars have a different frontspring diameter when compared to 1964-67 front springs ("KnuckleSandwich", Hot Rod, 6/87). 1969-present springs are based oncomputerized data concerning chassis package and bodystyles, but therates vary, in which a softer or stiffer ride is preferred.Note: 1964-67 front springs can be found on 1967-69 Camaros and 1968-74 Novas, but the spring rates will differ. 1968-72 A-body frontsprings are used on 1968-70 BOP full size cars, but the spring ratesvary.REAR SPINGSThe data that is true for front springs is the same for rear springs1968-72 rearends use a cup, and is flanged to hold the spring inplaceFRAMES*1968-72 frames had two different wheelbases, a 116 and 112 inchwheelbase. Sedans , station wagons, and utilities like the El Caminoused a 116 inch frame, and the frame is interchangeable, except thatthe sedan had non-boxed rails

No, you will have to buy a complete Parts car if you can find one. Paul.
