Ok guys I'm getting ready to buy my t3550 next week. What I need is an exact list of what I will need to swap this into my 96 GT with a t45 getting the boot. Before you scream SEARCH the archives I should tell you I already have and I have gotten mixed messages. I know I need the 4.6 bell ( I am going with the tremec aluminum bell). What else is needed? Some people say I need a new driveshaft, others say I just need the yoke. Do I need a driveshaft spacer also? What about the crossmember? Any modifications? Will the speedometer be off? I have 3:73 gears and the speedometer is corrected. will this remain the same with the t3550? TIA.
