BNCR has a 2-perf kit. They're expensive if with the true 2-perf  
plate, and much less expensive if with a matte.

The Mitchell 2-perf kit is Academy-centered, meaning its offset  
0.1000" for sound, plus the image is centered within the 4-perf image  
area, meaning the reg pin is two perfs down from the bottom of the  
image, not 1 perf down.


I know of no 3-perf kit for that camera.

Going from 4-perf to 2-perf is easy as the worm (and the worm gear)  
which drives the sprocket is changed from a "single-start" worm and  
gear (1:1 ratio) to a "double start" worm and gear (2:1 ratio).
