but I already tried that site and didn't get a reply.
Roger Bolick sent me an e-mail with helpful info (thanks Roger!!)
The Chevy Tech I spoke to yesterday says he can change the seal without removing the diff from the car, but it'll take at least a couple of hours, and @$75/hr shop rate.......
So now I'm thinking maybe I'll pull the D36 diff out myself and have shorter gears (3.73?) installed along with new seals....
or maybe even upgrade to a D44..... anyone have a D44 rear for sale or trade?
