I'm looking to put a built T-56 in my 2002 GT. I know that I need a new crossmember and to hook up a switch for reverse. I also know that i need to chop my driveshaft 3/4 of an inch. Well I want to keep my stock driveshaft incase I want to go back to the 5 speed transmission. What is my best way of going about this??? Is there a car at the junk yard that I can find with the propper demensions and still hold the power? or would I be better off to buy a driveshaft from jegs and take it to a machine shop and have it cut and ballanced? or is there a company out there that makes a driveshaft for the conversoin without costing a fortune?
