I just bought a 8.5 10 bolt from the junk yard for $95 dollars out of a 1986 olds 442. I believe it is a non posi unit with a 3.73 gear. I was thinking of putting a eaton's unit in it when I was told that I could use one from a impala ss 94-96 which is a eatons from the factory. I wanted to know your imput on this would you use a used posi unit in your car to save a few hundred dollars. What other cheap upgrade could I do for the back brakes this is all going on a turbo charged fuel injected monte carlo ss.
