671 or 588 Posi Unit
I'm looking for a 671 or 588 posi unit for my 70 12 bolt.
I would prefer a 671 for the convenience of gear sets but would consider a 588 if it has a good set of Ring and pinion gears.
Thanks,
Rick

Monzaz posted recently that he still has a couple of the aftermarket posi carriers.

Hey I have 1 or possibly 2 of the 402277 diff carrier, if this looks like what you’re looking for, talking apples/apples, I can get more pictures as needed. A couple gear sets too

I have a 588 carrier and the 4.33 gear set that I removed from it. Parted out an axle that someone butchered and ran in a 1967 Firebird
