Yes, you do need the drive shaft. I switched from auto to manual. stole from donor the clutch master cylinder, clutch lines, flywheel and clutch assy, trans of course, shifter, floor plate and drive shaft. I spliced the wiring harness from the trans and everythings good. I had a little problem with my fuel system but that's all fixed now. Of course, my Pathy is only 2 wheel drive, so somethings were a little easier than yours might be but if you have any questions, just let me know. I know others on this forum have done this same swap.
