Hello Chris, the diameter of the friction control is 127,2mm (outside). The wheel has 36 teeth. The internal diameter is 17.6 mm. The thickness is 8 mm. The angle from the throttle arm is backward 25 degrees and forward 37,25 degrees. And - I am not sure - I think that the space between the consoles are 100mm. Hope, its helpful for you Martin "Pegasus"
