Hi, new to the forum, just purchased a 1967 Parisienne Convertible project, looking to upgrade the ride a bit and change out the worn suspension, (upper and lower control arms front and rear, coils etc...) , spoke to a number of suppliers and some retailers and most say the impala parts will fit but no o...

Hi all, I was considering selling my 68 2+2 this year, but only after I fixed a couple of soft spots on my frame. Along with help from "pont427" and a seasoned body man he knows well, we got it up on a hoist and had a closer look. We all agreed that the original frame was worse than thought and getting a better f...

Hey guys, I got a pair of 15x8.5 aluminum slotted rims and tried them on the back over drum brakes and it seemed like 10cm outside of the body. I saw few of you wear 15x8 on the back. Which seems too wide as well. So my question is - when you do drum to disk brake conversion, does the track width become more nar...

I'm sure these were early coil overs to assist weak springs. Have you seen them before ? They seem to be height adjustable.

Hey there. Does anyone know the parameters of 15 inch rims that can be put over disk brakes on 1965 Parisienne CS by any chance? I'm thinking of installing disk brakes and that will involve wheels change as well, as I believe someone said the original 14 inch won't fit. Also i saw on other forums that Rall...

Some Brake questions if you guys don't mind, Single to dual tandem on a stock manual drum system with a 6:1 pedal ratio. Do we keep the master bore the same as in the stock single reservoir? It's something I've wondered about. Lets say, the car has a 1 1/8" single master. Its a old 50 Plymouth, so that old s...

Hey everyone, i just got myself 1965 Parisienne CS in so-so condition and have tons of questions, will post them in corresponding forum sections: Breaks/Wheels 1. Are there bolt-on power disk break sets to replace drum breaks? 2. What would be the size of rally rims and tires if there are disc breaks?...

Here's one for ya'. On my 67 Grande Parsienne 4 drum system, who knows what size the bleed screws are at the wheel cylinders? I'm assuming they's likely be the same as Impala, but I can't find a listing earlier than 69 for Russel speed bleeders. 69 Impala drum system lists them as being 5/16 -24 x 1"...

Ok, It's probably been gone over before, but I'll ask again anyway. Why are there two lower arm frame mount holes on the 65-70? I've heard some theory that it's was for wagons to help the rear sit higher? But then had it discounted with other talk that a wagon came on the bottom hole. Better traction on the...

I spotted a 1977 Chevy Motorhome in the local junkyard last week, and it had a Hydroboost behind the master cylinder.
