Taking Measurements
Measuring from the inside portion of the Pro Throttle knob-end, there is comfortably about an inch and a half of clearance for the wheel pots to go without interfering with reaching the pinky button on the PT.
Space the wheel pots as far apart as possible to give you as much clearance as you can in moving the pots with your little finger.
Once you're satisfied with the spacing, make a template out of some thin plastic (I use a milk jug) which will be used to cut out the slots for the wheel pots.
