The bell-housing will have to be the same--bolt pattern and starter location. The flywheel will have to be changed, in an automatic it's a far lighter flywheel because the torque convertor bolts to it. Then the clutch pressure plate will bolt to the new, heavier flywheel. Then you will have to find a pedal assembly for clutch, cut hole through firewall and all the linkage, brackets and pivot points. Then, either swap out steering columns or much easier is get a floor shifter kit. If the transmission mount is in the wrong place, (different length total from bell-housing to rear output) some fabrication may have to be done (hopefully not, may bolt right up to old mount and crossmember. Then driveshaft length if different..but that's actually easy, a shop can shorten or lengthen, and balance a driveshaft. Last, the final drive..if way different from the auto, the Third Member may have to be made right.


This is flywheel for automatic


Clutch. Not exact ones but demonstrates the difference..the clutch disc must have a flat surface to 'grab'
