I would like to upgrade to a t-56 from a t-45 but im starting to think that its gonna take alot of money...I know I need a new driveshaft, crossmember...ect....what else do i need for me to be able to stick one in my car? Can i use one that came out of a 03-04 cobra? What all is require guys....if you can help or atleast know of a place that can help i would appreciate it...I know D and D performance deal with them but they only have a kit of 99-04 cars....help guys?
 
It might sound weird(to the manual guys at least), but I would do a built automatic instead of a t-56.

If you're into 1/4 racing, yes. But I wanted a fun daily driven street car so I went auto to 6-speed. Not to mention gas milage on the highway is a LOT better than when I had the auto + 4.10 gears. No regrets here, even though I kinda suck at the track lol
