I have a custom Happ Stick for sale for the 360 it has QD’s so you can easily change the buttons or the stick if you want. The only problem is you would have to take the Happ Stick out and rebuild it to get it to work because I screwed up somewhere when I replaced the original art and put the Gill art.
The Qd’s and rewiring was done by
Other than that it has no issues with it.
It’s $70 plus shipping
I also have some 8 used Happ Concave Buttons that I pulled out of a custom Ps2 stick and a Happ P360 stick that was used by a friend but he heavily screwed the buttom of it I’m not sure if it works but most likely it didn’t effect anything.
Buttons $5 plus shipping On Hold
Happ P360 $7 plus shipping On Hold
I also have a sealed copy of PGR4 for the 360 for $7
