Body tolerances were loose, some can be 1/2" off or more back when they were making these pop cans.
Enquire about thrust angle correction.
The ones I've done, the passenger spring needs to be shimmed forward to square up the wheel dimensions. This affects the god number, tracking straight is key.
Ya, the first screenshot of the factory dimensions above say that the measurements should be within 1/4", haha... I'm not a body guy, but I think 1/4" tolerance in a factory manual is a hell of alot of slop.
