down to the point----1997 lexus SC300, swapped Aristo motor, and did the wiring harness with DR. Tweak. In the end i found out from him that i cant use my SC300 tranny and i have to updrade to Aristo or Supra auto tranny. SSOOOO my question is-- if i get Aristo/Supra tranny can i use my current SC300 driveshaft, or get Aristo/Supra driveshaft, or get it custom done, or what??? Thanks a lot everybody
