This is for GM 10 bolt with 3.08 and lower gear. So it is for the 2 series carrier 88 and up 10 bolt. Brand is unknown because I bought it open box at Summit Racing. A clerk told me at the counter it was an Strange but that cant be proven. Thgis is what I can read of the part number STR-R5?2040-1(STR at summitracing means Strange so I am confident that it what brand it is.) List Price was 349 and I am looking to get $195 shipped or best reasonable offer. No reasonable offer refused.
Rememmber this is Brand New, never used.

 

someone wants this.
