For anyone wanting to convert the A body from 5x4 over to 5x4.5

I got off cheap. I bought 2 Chevy II 15x8 centerline ( they are biased toward the front for deep backspacing to fit similar chevy fender covered rear wheels) and drilled a 5 on 4 pattern between the 5 on 4.75 pattern with a hand drill! I cheated a bit and used some 6th grade geometry as I used the large 3.125 ish center register as a datum point and just used a divider set up off its ID to scribe a 5 on 4 bolt circle and used same divider to cut the 4" bolt circle into 5 equal segments. With drill in hand I drilled said bolt holes and then fabricated a centering ring for the Axle boss and the rim register out of brass on a lathe. Darn things measure almost no radial runnout and the rim is hubcentric so the lugs need not be 100% accurate as they are only holding the rim onto the register.
