T-45 swap to T-56

[Killerstang]

Hey i have a 99 gt with the T-45 transmission and was wondering if anyone knew how difficult it is to swap it out for the T-56 6-speed. when I looked it up all I could find is it saying there are slight modifications that need to be made, But I cant find what the modifications are.

can someone help me. is it something i can do on my own or not at all

for sure you'll need a new clutch, flywheel, shifter and bellhousing to go along with the new transmission. I believe you'll also need a new driveshaft, and I'm sure there may be other little odds and ends here and there that would be necessary.
