CLASS RACER FORUM - View Single Post - gm A-body wheel spacing

At the closest spot, the shock is about 1/4" to 3/8" from the wheel. I have QA1 shocks with the bigger shock studs.

I've been racing/tuning 68-72 GM A-body's for about 15 years, and that is the standard wheel that everybody uses. It's interesting, though, I had a '70 Olds Cutlass with the same rearend and suspension, and I could get a 29.5x10.5 bias slick in the wheel well with just a little "banging" on the inner wheel house and rolling the outer lip. On my GS, the outer fender is shaped different, so that tire won't fit up in the wheel well at my ride height. I think the Chevelle has enough room for a 29.5x10.5 bias slick on that wheel, though.

Hope this helps. Sorry for the ramble.
