A long time ago I almost bought one of those from Garys U-Pull it in Binghampton NY for $75. It was in an Impala I got some parts out of.
I was like WooHoo a 10 bolt posi rear for $75!!! (10 bolt, LOL
) I was THIS close to buying it until I found out it had 2-something gears.
Seeing as I'd never heard of a GM posi rear with anything higher than a 3 gear, I figured it had an open diff and someone welded the spider gears to make it a posi so I passed on it. I've never seen another one until today.
Now I'm wishing I got it anyway just to be different. I'd have one cool-assed 12 bolt rear end!
The way I see it is, if I can buy a HP cam for my Caddy 500, I'm sure somebody, somewhere
makes parts for them.
