Are the rear lower control arms the same on a 65 as a 67? Reason I ask, is I'd like to detail and put 4 arms together pre conversion for a 12 bolt. I'd like to do a 12 4 arm to replace the weak and worn 10 bolt 3 leg (and both are loose!!) I have a pair of nice 67's lowers from our good member Cliff already. And have...

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...

(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....

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...

I read in another thread about you converting your 66 to a dual cylinder using 36239 master. Just wondering how that job went and if you'd mind detailing in this thread the ups and downs of doing it. I figured it would ask in a new thread rather than contaminating the other one where the site member is look...

I probably already know the answer, but are the B, F41 big front bar brackets the same as the smaller bar? Yes, all good....If no, does anyone have an old pair of bigger ones? Also, is the bigger bushing a readily available part? Thanks, Mark

For my 69 disc conversion. If you have the parts, and like to do you own lines, then I think a simple mock up jig is a way to make it easier to pre fab them close to the correct shape and length. To me it's preferable than having to spend time in and out of the engine compartment. Plus it's a good way to visualize...

So I'll be soon converting the 69 to front discs, 69/70 single piston style. I'll need a disc/drum master so I order one. Advertised as "Front disc brakes, power brakes". I like this style as it seems to approximate what would have been under hood if the car came with discs. The price is good and I know wha...

When you find a Rock Auto closeout, C3 Rotors can be really cheap. I always said C3 rotors were inexpensive and a good choice when converting your B to disc, but I had no Idea they could be found at this price. Yes, they are China, and uncoated, but for this price I'll take my chances...and I still used the d...

Converting the 69 to single piston disc brakes. I have the correct hold off (well, 1970) and bracket. Question, Is there any special technique to bleeding the fronts with this valve in place.

Sunday, I will attempt to install the front springs. I have a high quality spring compressor but these big springs are intimidating. Wish me luck ! -- Edited by ABC123 on Monday 22nd of April 2024 06:29:41 PM -- Edited by ABC123 on Tuesday 23rd of April 2024 06:41:11 AM

The original front bolts for the lower ball joints have a disproportional oversize head. I never even thought much about it but it makes sense now. They are wheel stops! They prevent the spindle from hitting the control arm during a very sharp turn. They are missing in the white car but I know they are s...

Randy's thread about front springs prompted me to ask about rears for the same cars, 65-70 B body Canadian Pontiacs (or full size Chevrolets). Has anyone used the Cargo Coil style rear springs on one of these cars? I'm curious what it did to ride height? Also, has anyone tried a wagon spring in a sedan or...

Hey there, does anyone know torque specs for 70s slot mags on Impalas/Pontiacs?

I need to clean a set of these up. But which ones are correct ? The white 69 has the set with the donuts. Of course when I took a shot of them, more bad news.
