The 12 bolt is like new with 3.73 gears i bought it from a guy who never installed it. only bad thing is the drum brakes so i will be replacing them soon and using the 12 bolt thanks fellas.

Might have already been set up for drag racing ie: spool, numerically high ratio so it was problably a bit cheaper to go with the 9.
