This might not help tbe OP but Ill add my two cents. It seemed like the first years of Dodge outer wheel houses from AMD were thicker and heavier than the ones you get now which feel lighter? I dont know which is better but I used one of the first offerings, the heavier ones, and I didnt use the alignment hole. I remember having to rotate the wheelhouse forward until it fit the quarter nice and then once tacked I trimmed the excess from behind the rocker and drilled a new alignment hole. I do have some of the lighter ones as I call em but have yet to use them. But yeah the old inner and new outer fit good on the flange.
