8.75 Not centered?!?!

just for fun, measure from the outer fender to the frame rails and see if you are off there

it could be your front hanger bushings are making it not sit right, with the offset shackles in place, but i would guess your just seeing slop in the build

production and assembly tolerances are a lot tighter then they used to be, and what your describing isnt unusual
Both sides measure 14 1/2" from frame to wheel well lip.
