I just converted my 88 supra to a 5 spd. I imagine it would be a similar process. You'll probably need the tranny, master and slave clutch cylinders, the clutch and brake pedal assemblies, clutch line, 6spd flywheel and clutch, possibly the cast iron bottom mounting brackets and the inspection plate covers. It took me a couple of days cause I was hunting down parts and it was my first time. You should be able to do it without pulling the motor.I did. You need to find out the differences, if any, between the bell housing bolt patterns, and make sure you have all the necessary parts. I think the auto diff. is lower geared so doing the conversion you should have better acceleration on bottom, but your top speed will suffer. Check your diff. gears to find what you want. Everything should just bolt right up.
