wut r some cars/trucks i can get a posi out of that has the same lug nut pattern and bolt right in

 

Assuming you're wanting to bolt into a 82-92 Camaro/Firebird, a complete list of ALL cars & trucks that have compatible rears is:

82-92 Camaro/Firebird



93-02 Camaro/Firebird bolts in, but there are some detail differences.

 

I think you can use an S10 posi, but i'm not sure they have halfway decent posi's anyway.

I'm not sure if there are any other GM vehicles that got the 7.5" 10 bolt, and may have has a posi from the factory...?

just make sure you match up your axle spline count with the axles you want to use, and match up the series with the gears you want to use.....
(just like was mentioned in your last thread, on the same topic...)

 

- Some astro vans had a posi, but few and far between. Most of the astro's and S10's that got posi were the gov-lock, which isn't worth the effort of installation.
NONE will "bolt-in". All will require proper gear set-up, factory or aftermarket. - lug pattern has nothing to do with posi installation. If you ment complete rear with posi, then as stated:

 

well now mike doesnt seem like you need to ask this no more, being that you rear end started being posi now. lol

 

MOST 82 & up GM RWD cars got the same 7 1/2" / 7 5/8" rear end, but only a select few got posi, all posi rears had a metal tab on them from the factory saying "limited slip diff fluid only" located on one of the bolts on the cover, if it has that tab it came from the factory with a posi. My suggestion is to go to the bone yards and see if you can spot these tags on an appropriate year car, bear in mind that GM switched the axles from 26 to 28 spline around '88 or '89, and make sure it's a 10 bolt...there are 9 bolt rears out there...mostly on our cars but I did see one on a Monte Carlo SS awhile back, so they are out there
