I want to repair this clark cyclops. It had a jackshaft at one point with right side chain to wheel. Now it has direct chain on left side badly done. Gc160 is set to right. I would like to center the gc160 better and replace jackshaft. Thats complicated with torque converter, which is my preference. The driven unit on jackshaft doesn't appear to be reversible so gc160 has to be moved to left. Has anyone done this well or is cent clutch better choice?
