Centering the rear wheels

Local guy here had a 70 dart street car, 440 tunnel ram stick car. He put new quarter panels on the car and moved them forward all the way to the tub, left the rear end where it was.
I did the same thing, took my time and made them match a template, they fit tite up against the inner front part of the wheel house. My painter/body man had VERY little work to do on them. Looks stock if u don`t know better . running 295 65 15 `s on it.
