(Online photo, not mine) My car has been on the hoist for 4 days now ! The problem is the rear flex line where it mounts and passes through the frame crossmember. There is a retaining clip for each side of the frame. Every part brought in has the clips too close together as if the cross member is too thick....

Had a nice visit this afternoon from CP member Cliff (oshawacliff), who has a gorgeous Oshawa 67 Impala FB.He's been trying to find replacement rotors as his car has the 4 piston disk brakes. He brought along the supposed 67-68 direct fit rotor from Ecklers he purchaced. What we discovered is th...

CP'ers For reference, perhaps someone can use this someday. For anyone who has converted their 65-70 B Body from front Drum to Disc, or even to Disc Disc, you know that unless buying a complete system or kit, finding the correct tube nut sizes takes a little research. Even on the same line size, apparen...

Corvette rotors on 69-70 Canadian full size Pontiacs. A few years back, upon starting my chassis restoration, I had decided that my 69' Parisienne would need disc brakes in place of drums on the front. A little more performace would demand that braking be increased as well. Remeberi...

Just received my re-chromed bumper and I don't want to put the old bolts, I want new ones. Does anyone know how many I need of each for a 67 Parisienne? There are 12 in the front & 4 in the back bumper. They are a mix of 1" and 1½" and I'm not sure if 5/16 or 3/8 assuming they are all the same width. What I am su...

I recently had a good look at my upper control arm bushings and without a doubt, these upper bushings are toast. The rubber is squishing out and the rubber hole is elongated and there is a lot of play in the bushing itself. So, I knew this day was coming that I would have to address the front end bushings (...

I'm trying to remove the front bumper. The parking lights & housing go through a bracket that only so the wiring stays in place but the housing won't go through. I need to disconnect it. Any ideas where? 67 Parisienne.

I have been researching a bit on upgrading my steering box to a 12.7 to 1 ratio for quicker handling responses on the 68 Grande. From what I find is that everyone that upgrades the box comments on the upgrade as being positive. My box is not leaking but it is the standard S Saginaw box with a 6 on it, four b...

Hi everyone, is there a top and bottom side to the front springs? Mine dont have any white or yellow marks like I read in a post. They look symmetrical on both ends. I also read a post that said they can only fit in one way. It's on a 68 Parisienne. Thanks

Hello all! So I have a 1966 Parisienne, Canadian model, and have had it in the frame shop for some adjustments - passenger side was sagging and turns out it wasn't suspension as I thought before changing the springs. The guy who owns the shop, didn't have the exact frame measurement specs for my car, s...

Finally got around to installing the Viking hybrid coilovers I'd bought a while back. Breaking the front end apart on the B body is a job nobody enjoys, and I'd done it far too many times trying to find an optimum spring rate. Seems replacement springs are far too stiff these days, and it's rare anyone ca...

Ok so what started out as front brakes on my 65 Parisienne has turned into bearings, seals etc. The problem I have is the seal and or gasket that should be at the front backing plate and spindle were badly worn.

I've had a rebuilt and replated booster on the shelf for years now, and since I'm about to replace the master, converting to a 1"bore from a 1 1/8", I'm thinking of using it as it looks so nice compared to the original one (which currently works perfect anyway, just ugly). Is it a big job to replace the boos...
