Jeff I'm not sure how you can achieve it to fit both motors. I'm not sure how critical it is to get the pulley height correct, belt is fairly long and will probably accept a bit of misalignment . I will put the pulley on a F/C and get a measurement from the slasher base to the center off the "V" so it gives you a measurement to aim for. I doubt once set up you would ever consider going back to a F/C, there is a lot more PT's out there now
