I’ve been looking to update the rearend in my 66 special and kept looking at $3k+ prices for anything I came across. Decided to hit the swap meet in Moultrie Saturday to look some more. A buddy of mine saw a post about us going and what I was looking for and it turns out that another friend had a built 10-bolt from a 65 cutlass that had an Auburn posi and a 3.90 gear in it with just a few miles on it since he installed it. He decided it was too much gear for him and went to another complete rearend with a 3.31. I’m using a 4L60e so the 3.90 is perfect for me! Best part about it…………..$350 for the whole thing. Another puzzle piece put together!
