Off the wall question but the 57-64 Olds rear ends were a very popular swap for gassers back in the day. My 36 Chevy 5 window coupe has one. I've got all the parts gathered to rebuild it and a set of 4.10 gears to replace the pitted 5.38s that were in it. The last thing I need to locate is a pair of brake drums. I've read somewhere that certain years of Chevy 1/2 ton 2 wheel drive drums fit but can't verify. All sources I've checked have no listing other than Fabcraft and they are pretty proud of their stuff. Can any of you old timers who ran these rear ends offer any advice ? They are 11x2 with a 5" bolt circle.
