does happen, I uncovered my 12 bolt from all the plastic bags I taped on it three years ago and whala .... I hit the jackpot w this 12 bolt I bought. The seller had it under his Firebird and said it was professionally rebuilt and never even had gear oil in it, he was correct.
Take a look ... I think I'm ready to go, gonna take off the perches and prep it for the Ride Tech air bar install, its on order now, I'm totally stoked (if you couldn't tell!).
I do appreciate all the comments but, .... for the price I paid for this 12 bolt I'm keeping it fer sure, not sure what size spline the axles are.
She'll do fine under my Camaro.
Thanks for looking ....
