I've got a '62 dually that had the original lock ring type wheels on the rear and newer one piece rims on the front. I wanted to replace the rears with one piece rims as well but here's what I found out. The inner rear wheels need to be the flat base type centers to clear the brake drums and the more modern rims are drop centers which won't clear the brake drums. So what I've got is the newer one piece rims on the outside rear and the old flat base on the inside rear. The newer rims are hub centric and I didn't have to change the studs.
Running radials up front and bias plys in the rear. So far, so good...
