yes please, i am using the 2speed rs4 and not sure which truck's gears i want to use, at the time i have the 11/15 final drives i think but want the diff's and the tranny to be nice to each other. my email is adaynumberone@yahoo. i have a friend with a 3.3 jato and it's fast but to hairy out the hole, but i really would like to stop his heart when i finish this MT2.
