I have a friend working to restore his 63 big brake ZO6 car. He had a question regarding the correct part number for correct drums. I believe the part number is cast into the drums. I have a September 64 Chevrolet Dealer parts catolog that show two part numbers: 3843900 & 3841831 both listed as front. Not sure if that was a misprint or what. Is there a part number for the rear (or do they just use the same drum)? Any thoughts I can pass on....
