Not sure what the interest is here, but I know there are a few 720 joystick owners.
I've repro'd the roller and lower ball in Delrin and only have a couple left.
The roller is the newer preferred style for all 720 owners.
I would like to sell them as a kit. 1 roller and 1 lower ball for $30 shipped.
If there is more people interested, I will consider a second run.
Also, willing to work out a trade for a Ram Controls Pivot Ball.
