Exclamation 68 firebird ... rear end seems off center ?

Hi guys,

I was measuring the rear fenderwell clearances on my 1968 firebird to decide for a wheel spacer and noticed that the right wheel sticks out about an inch more towards the fender lip than the left wheel. Also noticed that the right wheel is sitting more towards the rear of the vehicle and the left wheel more towards the front... Has anyone heard of a such misalignment situation? It could just be the rear fender sheet metal, but I don't think so, this used to be a straight car, no sign of accidents or anything. When the snow is gone, I will pull the car on a lift and take measurements from underneath. Until then, does anyone have an idea? Could this just be standard tolerances?

* I have 255/50/ZR16 tires and 16" AR TT2 wheels, both with same width and backspacing, nothing wrong there.
* Standard rear drum brakes
* Hotchkis sport leaf springs (about 1.5"-2" drop)
* Bilstein shocks
* Hotchkis rear sway bar

Are your u bolts over the leaf springs still fully tight? You should be able to tell by looking at the springs if any shifting has taken place. Bob

Not a problem.
My very first car was a '68 Firebird 400 4 speed. It had 40,000 miles on it when I bought it for $450.00 and drove it home from out of state back in 1977. That was one car that looked 20 times better when I sold it than when I bought it several years later. I even pulled the engine out of it just to repaint it, apparently I had to much time on my hands.... lol Bob

There should also be a stud hanging out from the middle of the spring to locate it on the rearend. That could be sheared off. Bob, do you remember that 68 Camaro(vert) we had on the dyno at the old shop. That had the exact same problem!

I do remember that, that could be the problem here. It would be a good idea to check it out. Bob
