hey i have a 95 grand prix se and i was thinking of swapping my tranny to a manual, i was thinking the 5 speed from a lumina but wouldnt i have to swap to a 3.4, or is there any way i can keep my 3.1 and swap trans? also i was wondering if there was a mount that would let me hookup 2 alternators as i will be needing 2 with about 250 amps each, i am building a show car. any information on the tranny and alt helps, thanks all.
