I have done several T-5 conversions. The input shaft on a T-5 is 5/8 of an inch longer. You can use your stock bellhousing, clutch, linkage and everything with an adapter/spacer for that T-5. Yes, the rear cross member has to be modified, and the drive shaft will need to be shortened one inch. You'll love the 5 speed, but you might want to put some gear in the car if you haven't done that already. 3.55's are great. Oops, I just noticed that yours is an automatic? Shame on me for thinking you already had a three or four speed car.
