Bump back to the top... anybody know the difinitive answer? Will a 4-door frame bolt up to a 2-door body?

I found some info on ASK.COM   there is concensus, that the 60 Chevrolet all use the same frame...  presuming 60 Cdn Pontiac is the same

This is from a photocopied Chev manual that came with my GM canada documents.

Number of cross members ---------------------- 4
Sidemember Section:
   Moduls (in3 ) ----------------------------------1.09
   Moment of inertia ----------------------------4.27
Maximum Overall Lengh (Aprox.)-----------195.3
Maximum Width (over sidemembers at rear cross-
member)------------------------------------------47.5
Convertable Frame----Steel plates welded to
 top and bottom of sidemember and centre beam
Body Mounting Points:
  Total, all models except convertable----------8

This from the Pontiac Brochure.
WHEELBASE-119". Front and rear tread, 60.3" and 59.3". Overall: length 212.22", width 80.7", height- Sport sedan and sport coupe 54.0", sedans and convertable 56.0", Safaris 56.3".





As soon as its warm enough I'm going to chuck a 4 door body away and compare the frame with mine to see if theres any difference.

I would say yes and no!  Yes the frames would be the same, however the four door models may have 2 or 4 more body mounts(I'd say 2)!  The bodies would sit on the chassis perfectly except you may have a couple of extra frame to body mounts not in use if you mounted a 2 door on a 4 door frame.  Think about it for a minute, would GM rather build 50 million frames(exageration) all the same/similar or build a different frame for every body style, the re-tooling would have bankrupted them alot sooner if they did.  I built a 57 Chev 150 two door sedan on a 57 Chev 210 four door frame.  I would say GM probably had 3 frames in 1960 that were very similar but not the same.  (One) would be a convertable frame(no metal roof, stronger frame)................(The second) would be for the 2 and 4 door Sedans and Hardtops........And the third would be for the station wagon.......buuuutttt I may be wrong on the station wagon.  I'm thinking the wagon is longer and maybe a different section of frame behind the differential.  Gas tank mounting, spare tire area etc!  As we say in Alberta..........Just Giver!!!

Frames are essentially the same, and in that year both the sedan and the wagon had the same wheelbase.

 If you're refering to the little picture of the gold coloured one it is just a pic I found online. Mines not that nice yet, you can check the registry for a pic of mine.
