ok here's the deal I got a 1992 240sx hb with auto transmission. I also have a 5spd from a 89 240sx along with all the hardware. (the 89 was a wrecked car so i can strip everything) now just a few questions: #1 will the flywheel from the 89 fit on my 92 crank??? #2 which ecu should i use the 89 or 92??? #3 will I need to change the driveshaft aswell??? #4 and if i do would the 89 drive shaft work on the 92???

well that's it thanks for your help in advance.
