[mitchDublin]

Hi all, I'm based in Dublin Ireland, spent last 3 years working on 72 440 barracuda.
I replaced whole suspension, usual track rods , shocks , heavier roll bars etc .
I was looking at rear of car today and noticed that my passenger rear wheel in set about 2.5 inches inside fender, drivers rear wheel is approx half an inch inside fender , looks to me that rear body of car is about 2.5 inches to the left . Not level side to side . Has anyone please got any idea why this would be like this

I would measure the axle perch to backing plate on each side, to see if there's a difference. These cars weren't built to very tight tolerances, some offset is to be expected.

Hi, thanks for reply, I had a look underneath, leaf springs look same, bolted to body frame , I also looked at leaf rear mounting points and they do not look like they had any damage over the years, everything looks like it in place but rear wheels are definitely to one side , it's noticeable, closer to one fender than other , tell me if I'm wrong, but if I just move axle to one side and centre , that could affect driveshaft alignment??

Reading your description, it sounds like it's shifted 1".
Have the quarter panels been replaced?
Is this the original rear end?
Maybe the spring perches were moved/replaced at some point.
That's why I mentioned measuring the distance from the spring perch to the brake backing plate, it should be the same distance on each side.
