I know that there are differences in the 55 2nd thru 59 Chevy and GMC rear ends but wondering about drums and cables. Swapping out the stock 3.90 rear in my 55 2nd for a 56 GMC 3.08 Spicer unit. Doing some research on a GMC site that says the drums and cables are near impossible to get. Numbers in the parts sites plus my local parts store, show no difference and now I am asking the experts. From what I can gather, it is an easy bolt in with only some brake line bracket changes. I was hoping to use everything off mine as in backing plates, shoes, drums, cables etc. Anyone try this?
