OK, it sounds like you guys know about obsure posi units! A few years ago I pulled the guts out of a rear end I was told came out of a 1968 full sized Olds. It has the number 700 cast into it and it has 12 bolts holding the ring gear on. It's a 2.56 ratio and it has the "S" springs holding the clutches in, not the round coil springs. I believe the axles had 31 splines. The bone yard wanted a pile of money for the whole rear complete, but sold me the posi unit for about half that price. I'm sure they threw the rest into the scrap pile after that! So... any idea what it really came out of and will fit

Don't mean to highjack the thread, just wanted to get this question to both of you and this seemed like the easiest way!
