16" steelies for 67 k-20

[ChevyTruckGuy68]

Hello everyone, i recently made a post about this in 4x4 with little response. I have a 67 k -20 with 16" steelies all the way around. Front drums don't like these 70 / 80's era rims. The outer edge of the drums ride very close like 1/500th away from where the rims are riveted or welded in the center.

Any recommendations for new rims or modification would be greatly appreciated,

Thanks Andrew.
