- 1956
I was thinking of upgrading my 1956 rear end to a 1957 so that I can use the multiple ratios available for the 9 inch. I did this upgrade on my last 56 in 1970 because I was drag racing it. On my present 56 I just want the flexibility of the 9 inch ratio availability. Does anyone know of an available 57 rear? I need the complete drum to drum to make this swap.
