Hi guys. I don't post much on here, but I sure have learned a lot. My buddy and I are just finishing a restoration on his 59 1 1/2 ton truck . We pulled the front brake drums and they are shot. We have not found replacements available from our sources. Do any of you know which years share the same drum/ spindle size? I know where there are a lot of parts trucks, just don't know what years may interchange. Thanks, Paul
