like he said, good luck.
Another thing to think about is that the t-56 ratios aren't very steep, compaired to the t-5, with one exception being 1993. You may be disappointed with your acceleration after the swap, also consider the t-56 is a heavier unit too.
t-56 (1993) First 2.97:1, Second 2.07:1, Third 1.43:1, Forth 1.00:1, Fifth 0.80:1, Sixth 0.62:1
t-56 (1994-02)2.66:1 first, 1.78:1 second, 1.30:1 third, 1.00:1 fourth, .74:1 fifth, .50:1 sixth
t-5 Gear Ratios: (1st) 2.95:1 (2nd) 1.94:1 (3rd) 1.34:1 (4th) 1.00:1 (5th) 0.73:1
