Where can I get a posi for a Monza diff

Postby wally409 » Sun Nov 11, 2012 4:17 pm

I have the running gear from a 76 V8 Monza that I'm putting into my 72 Vega. The rear diff is non-posi and I'd like to know what GM rear ends have the posi unit that will fit mine. And does that include the S-10 rear? There should be quite a few available. Please let me know. Thanks. Wally

You can use a posi out of an s-10, a 3rd or 4th gen camaro, or any G-body car as long as these cars have a 7.5 or 7.625" rear. Be aware that some use 28 spline axles and others use 26 spline so you need to make sure the axles you use match your carrier.

Thanks Roy - that's the information I need. I copied and pasted into my "Vega To Do list". :D
