In my pinion, if you are going to use the standard F-P transmission, you should use the standard F-P coupler.

The best part is from the Jeep model as I recall because they have 10 spokes rather than the more typical 5.

Also, drill the shaft out from the strange dim. that the axle of the Jeep is to something normal - 1/2 inch works great in my opinion.

To attach a sprocket to the coupler, I recommend bolting (or welding) a sprocket to a thin disk that is the size of the ridge of the coupler (about 4 inches in diameter) and then bolting that disk to the coupler. It has worked great for us in the past. See the picture below.
