I dont think it would even be worth the trouble. I would either get a t5 to replace it (if the stock one is busted), or just get a g-force/tko/3550/tko500/tko600/t56.
The 3650 is a stock trans and they had issues as well and I dont think the 3650 is realy any stronger than the t5.
You would prob. need the driveshaft out of a 01 or whatever year they went to the 3650 or at least check to make sure its not going to be shorter/longer. I want to think the 3650 is longer than the t5 but that could be cause' of the attached bell on the 3650.
