WTB: 61 to 64 Olds F/S 2.56 Differential/3rd members

Want to buy just the complete differential/3rd member - 2.56 ratio - generally found in the low end Oldsmobile 88 without a/c or in mountainous areas. Thanks. Ron

I probably have several rears from 63/64s. How do I determine what the ratio is? It's cold as **** right now but I can try and see what I have this weekend if I know how or what to look for. Where are you located? Not cheap to ship I'm sure.
