Really need to know, guys! 
Tron restrictor is made for the Tron stick. Without looking at the bottom of the Ultimarc trigger stick I can't say for sure but I am 99.9% sure you would have to do one helluva remodel to get the Tron stick restrictor repro to work with that joy.
DOT does not use the same restrictor, that game is pure 8-way and also has a push pull spinner. There are three ways to get a push pull spinner if that is what you want.
1) Find a DOT, Zwackery, or other push pull original spinner CP and harvest it
2) Buy an Apache Control push pull
3) Find somebody who is totally down on their luck and thus willing to sell you their totally awesome Turbo Twist High-Low since Randy of GGG is out of parts to make more.
I have a TRON CP. It is untested and unclean as I just go it but the mechanics on the trigger stick are in good shape. The leaf switches have good movement and the rubber grommets are still supple. No idea if the spinner opti board works but all part are there. All it should need would be an optipac and a good cleaning to rock and roll. PM me if interested.
If I was going to rock a frankenpanel I would make sure that the Tron joyrod was present and accounted for. Committing to a frankenpanel with a Tron substitute just seems to not be worth the trouble.
