I have an 83 Chevy C30 mason dump dually. It has a 14 bolt dually rear end and I’m having trouble with one of the brake drums. (I bought it like this). It has two different brake drums, and on one side the inner dually wheel won’t slide all the way in. The wheel hits a lip on the drum and on the other side no problem, but the drum doesn’t have the lip there. I have looked everywhere trying to find one but everyone I find has the same lip that won’t work. Does anybody know what drum I need?
