How is your tranny and clutch gone, what did you do? If your going to replace your tranny get an 01+ ACR/R/t 3.94. Don't worry about the SRT tranny no need for it. It will bolt up, you will need SRT axles. I know the imput shaft is differnt ont he two trannier and I am pretty sure there is an issue there. Just get an 01+ standard 3.94.
