Only 89-up (more or less) have the 28 spline axles. If you have a 82 rear, that posi will not work unless you replace the axles.

I don't know about SLP putting in my posi... I've put in every one I've ever had myself... it's a pretty simple, basic kind of thing.

The chance of finding a 90-92 f-body to get the axles is slim. The production figures were low for those years compared to the earlier years. I'm not saying they're not out there just that they're hard to find. Chances are if you do find one in a junk yard, they may ask a lot of money for the parts.

You can buy aftermarket 28 spline axles that will be much better than factory ones for $125 each

Contact www.drivetraindirect.com

Part number is KAC7-A7

They'll fit in all third gen 10 bolt housings that have a 28 spline carrier and will fit drum or disk brakes.
