Anyone identify this posi unit
 

the add just says 8" 28 Spline posi , 10 bolt. Part # J509368

I've done a search but come up with nothing. It is for a GM just wondering if it's for a Chevy 8.5 rear end Thanks

Thats really hard to say with out knowing more about it.... year range, bearings, ring gear bolts...which looks like 10 if Im guessing right from the pics. Its 8.5 or smaller for sure with the 28 spline axles.

Thanks. It's for a 95 Camaro
