70's era 12 bolt Posi tough to find?

[siggyfreud]

Hey all,

Searching for a rear for my truck. Trying to convert from 8 lug to 5 lug. Went to the Portland swap meet, walked around for nearly 4 hours and didn't find a potential rear.

I found a few on Craigslist locally:

http://salem.craigslist.org/pts/4392592465.html

However they are both open diffs. Are Posi's difficult to find stock? Worth buying one of these and replacing the carrier and ring/pinion with the gearset I want, or should I hold out and find something with a posi unit already? Not sure how rare they are, so hard to know which path to take.

Thanks!

The good Eaton style factory posi's are not easy to find. That one for $300 looks to be in much better shape, especially if they have the receipts for it. The one for $200 has obviously been sitting outside for a while, and could be rusty inside.

Think it's worth the money to grab it and throw a posi carrier in?

I put an Eaton cone-clutch unit in mine years ago.

I would as long as the inside checks out to be as good as it's supposed to be. I used to sell good used 12 bolts with unknown mileage for $125-150.
