Rear Axle slightly right

Adjusting the upper control arms will move the rear left to right as needed. Measure between the tire and frame for a good centered location.

Each upper arm have to be the same length. Do not make one shorter and one longer to move axle over to one side.
Acceptable on a panhard bar set up.

Most likely a tire to body difference on side to side IS the body. Find the centerline of the car and if the axle is centered to this, all is good.

Appreciate all the knowledge and advice.

Just did an 8.8 swap in my 85SS with adjustable uppers. You can adjust the rear upper control arms and it will pull/push the rear end from side to side. I measured from the inside of the rim to the frame rail to get it basically the same both sides. Then set the pinion angle. This video helped explain things.

. I see you have adjustable arms in that package.

That’s a great video!

Something could have been changed being it was modified. My 70 Cutlass is 3/4" to the right. I thought it looked uneven. Putting on 275/60R15 proved my theory. No damage, just the axle is to the right, body related. When I replace the rear quarters, it will get fixed. Inspect and measure.

Measure from the wheel well to frame on both sides. If they are within an 1/8-3/16", then center the axle as Mac described in post #11, then head off to the alignment shop.
