(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...

Does anyone have a good part number for 70 B Body brake rotors? The Centric number is 120.62066 but when crossed over Raybestos, Wagner, or Winhere all come up with rears for a Pontiac Montana. Cant find a number using application with these companies either. Any help with a good number would be apprec...

I was wondering if someone could take a picture of the rear flex line on your 67? After looking at pictures of new lines on RockAuto and the Hubbard Impala catalogue , I am convinced the previous owner installed a flex line for a 69 or 70. From what I can tell the 66 67 68 line screws into a T fitting the 69 70 li...

I bought these 2 kits so I could check the pressures on the front calipers. Turns out they didn't get used.. Can anyone use one or both. 30.00 for pair SOLD -- Edited by oshawacliff on Wednesday 1st of May 2019 06:56:20 PM

dumb question, does anyone have pics of how they routed the brake lines when doing this conversion, the rubber vette lines are a few inches too short

Mods are not an easy find... Nearly 9 years ago, with a lack of patience and research skills, I ended up being the wrong disc brake spindle conversion kit for my car. Several years later, I met a guy at the place I work at now, who has a Caprice, same year, has the conversion on his car. Found out where he got...

I am thinking when I do my engine swap I will likely need to change front springs. I have a pair here I bought from Mark (Cdnpont) and may try them. I was doing some online reading tonight and found this on a Chevy forum. Has anyone else experienced this, where the replacement has more coils than the origin...

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 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.

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...
