1968 GS rear for 72 Rivvy?

I'm looking into getting a 3.42 posi rear put into my 1972 Riviera and was curious as to what make/model would work? I found a 1968 Riviera GS junker with the rear end in it, but would that work? Anybody have any ideas or suggestions?

Thanks, Nick

 

A 68 rear will not work :shock:

:Smarty: the only years you could get a 3.42 posi was 71 or 72
and they are tough to come by

I put one in my 72 riv and it made a big difference

yours is the 9 3/8

If I could find a 2.93 posi I'd probably change it back...... but i'd never put an open diff. back in it

how about other gm models to fit in there?
