posi unit

Hi, im looking for a 8.5 corporate posi unit 28 spline or a powertrax, any help would be appreciated. chaz

 

You may want to try and contact Gevo's Rears & Gears. They always advertise in Hemmings in the Chevelle/Camaro parts for sale section.
That's where I bought mine back in '98, and I think it was about $225 rebuilt w/o exchange.

 

Here you go.
