Front suspension height

This is the info you need for the ride height

View attachment 1716224481

The factory set the ride height using the difference in measurements from the bottom of the torsion bar adjusting blade and the bottom out the lower ball joint. For an A body that’s the “V and L” car line (valiant) so 1-7/8”. They didn’t use any of the body parts as a reference, almost like they knew the body tolerances were big!

The real question I have is, what wheel and tire combination are you trying to install?
So... long story, not so short, I'm trying to get this thing closer to stock, or at least a stock look. Changed to discs up front going to a 4.5" bolt pattern so I bought 15" rallyes. Original bias ply's were 25.9 with 8.25 section width. My dilemma is I REALLY want Mickey Thompson tires to match the era but the smallest they make are 215/70 15's. They are 1" taller and a 1/4" wider. from what I read that's probably pushing it but I look at is as essentially 1/2" on each side for height and an 1/8" on each side for width. I do have a feeling I should have gpme with 6" rims though instead of 7's. Very few companies seem to be making tires now in 15's that offer a wide range in size since I am going to be running wider on the rear. Goodrich does but They have a long bad history of of the letters turning brown and have gotten expensive. Could go with Coopers but it feels wrong to have tires on a Mopar that say COBRA on them. I want to run RWL's also so I wouldn't want to turn them around. There are a couple of Japanese brands but that would bother me too. (Yeah, I know I got issues, LOL) T

So the very short version:)... 215/70R15 on front, 275/60R15 on Rear.
