Texas01GT

hey everyone i was in the process of getting a new clutch when i found out i needed some info that i didnt know...im pretty sure i have a T-45 tranny, i have a 2001 GT and the door tag says build date 02/01, and where is says TR, there is a 6 below it, my question is do i need the 10.5 inch clutch or the 11 inch?

P.S and just to double check...i do have the T-45 right????
