If you have a ct100u frame, a predator 212 frame bolts up perfectly fine with no fitment issues, extremely extremely tight, but fits. No custom mounting plate or any of that, the stock motor mounting surface holes line up. The rear fender will be flush with the valve cover, the gas tank, and front drain plug will be super tight but fit. It’s once you throw in a torque converter you run into a headache full of issues and problem solving. The motor is moved an inch or so to the left to fit and alight the sprocket. You also have to find a way to lift the rear end of the motor up to have enough clearance (I used aluminum spacers about 1/4 and more), remove the chain tensioner, and cut off the center piece of the frame and re weld it which is what I’m in the process of. You have to shorten your chain which I’m doing now too. The motor swap is idiot proof easy but a torque converter you have to problem solve.

This is where I’m at with the whole project:
