4 speed swap

My 63 dart is originally a 3 speed on the column with a /6. I kept all the parts when I went to a 318/904 auto. I was wanting to know if my clutch pedal assembly and z-bar linkage would work on a 4 speed swap? Also what other parts would be needed.....I know i need the bellhousing, flywheel, clutch,pressure plate, tranny,shifter,linkage,.....Do I need any special components for the pilot bushing? I heard that the crank for a auto verses standard are different, Is that true? I haven't done much homework so any help would be much appreciated. And finally, what tranny do I look for to do this swap? Any websites that would help me out?
