i am no expert on H wheels, however, where is the center hole measuring 2.750 ?
in all my years of playing with mopars, the hub register has always been 2.800-2.810, with the wheel center id being 2.812 - 2.820.
was that printing a misprint or ???? if indeed the center is 2.750, i don't believe that wheel will fit.
being in the junkyard business in the early 70's, it became quickly obvious that ford wheels had a smaller center register than mopar wheels, even though the bolt pattern was the same.
if i'm not mistaken, the ford register was 2.740 - 2.750 on the hub, and the wheels were 2.755 - 2.765. [or close to those dimensions]
