63 rear brake drum part #

[Todd L.]

Can anyone tell me what the part # is for 63 rear brake drums? I have looked everywhere trying to find a part #, even the 63 assembly instructions manual, and all it calls out is "brake drums". I have a few drums here and need to figure out which ones are correct for this car. Thanks so much!

What you see embedded in the drum is the casting number. There were two finished part numbers, one for base brakes and one for J-65 that had a finer finish on the friction surface.

Over the years casting numbers changed, like when the max. diameter was embedded in later service castings, but basically most 11 x 2" Chevy drums will work on the rear of a C2 drum brake car, and front or rear on a C1 for that manner.

List all the casting numbers and sizes you have and we might be able to figure them all out.
