If you change the trans which is a good idea, get the rear end and transmission control unit. Get everything unique to the SRT such as heat exchanger, plumbing, pump remote mount and plumbing for the smog pump. You might even want to grab the dash and ignition and key just for fun as well as the front and rear calipers and rotors. Might even grab the shocks, springs and wheels and then send the rear hatch and body contol module to me.
