hmm im not sure,its a stock 82-92 rear

[Tru2Chevy]

They switched to 28 spline axles for the last few years. Might wanna double check what axles you have before you spend money on a new LSD.

thnx didnt know that i thought all 82-92 rears were the same and the 93+ were different

[Tru2Chevy]

Nope, I think they switched in 89 or 90. The stock posi unit from a 2002 F-body will physically fit an a stock '82 housing, as long as you have the 28 spline axles for it. They are all 7.5"/7.625" 10 bolts.
