I have a 1954 GMC 100 series truck. When I purchased it the previous owner told me that the rear end was not the original. I believe he told me it was out of a 1963 Chevy.

Took the drums off today and it does remind me of my 63 Impala, but that was about 25 years ago so I could be wrong.

I would like to know if anyone has any tips on identifying the rear end so I can purchase some brake parts. Looked the rear end over and could only find a casting number of GM 82.

Thanks
Bennie
