Good luck on that Micha,A good alignment shop can "Square" the front and rear wheels to each other.

In this instance the concern is not body panels, it's getting the rear end housing centered and square to the lower unibody.
There is an old timer or two with depth of experience to actually verify the physical location of suspension parts before hanging the alignment heads.....they're difficult to find however.
Example: you can get a decent basic alignment printout on a car with one of the front wheels pushed back 1" ( frame collapsed), as long as the caster is within spec a laser alignment machine and many techs can't tell the difference.
Get out your plumb bobs and tape measures, size still matters.
