question on diff swap
orginally my car was stock w/ a 1988 2.8L V6 and 3.42 rear end. it now has a 5.7L V8 w/ the same rear end but I want to put in a posi. I've read that some things changed in '88 for GM rear ends and wasn't sure what would or wouldn't work. After lookin around and readin this is what I found....a 3.73 Eaton Posi Unit 7.625" 10 bolt GM 28 Spline..... and I know that Auburn has the same thing. Would this work in my '88 bird? thanks,

yours has 26 splines axles. you will need to get 28 splines to work the that carrier. Or buy a posi for 26 spline axles. gears are the same...
