need wheel help

[DartMan48]

I am having trouble with the center hole diameter on 15 x 4.5 wheels to fit disc brakes. I converted from 6 cyl 5 x 4 bp drum brakes to 15 x 4.5 disc brakes and all the wheels I have tried will not fit over the hub. any advice?

are you trying ford rims? they have the same b.p. but smaller center register
