Ive got a complete parts list by just requesting a quote. The big one is trans crossmember and the shifter location. Mopars are offset to the driver's side and these transmissions have shifters that are at centerline. The mods that SST does puts the shifter to the left side.

If you could get SST to sell you just the transmission then you could just piece it all together and fab a simple crossmember. They also sell the pedals and the 4 speed hump. For an auto to man. conversion it may be easier (maybe not cheaper) to just go with the "kit". If you already have collected pedals and a 4 speed hump then I would piece it together. I already have the whole TKO kit installed in my car from years ago so I'm going to email them and see if they will just sell the trans due to the TKX being a replacement part for the TKO.
