I like to fabricate and have the equipment so I went ahead and made my own gust lock out of light weight 4130. This works whether the wires are inside or outside the control stick.
The threaded knobs are 8/32. I cut a relief in the threads on a lathe in the proper location and installed retainer clips to keep them in place at all times. The end that attaches to the seat pedestal is slotted 1/2" for the screw to pivot during installation. It also allows the gust lock to be extended and tightened up.
I installed an 8/32 plate nut under the seat pedestal. There is a 5/16" steel insert that is drilled and tapped 8/32 in the control stick TIG welded in. I used a small leather hole punch to make a clean hole in the control stick cover and used a dab of contact cement on the inside of the cover holding the hole location in place. There is also a metal anti crush insert in the gust lock at that location.
