Good luck on finding one of these - they are getting tough to find. I think SUZO-HAPP sells a compatible rotary stick but it doesn't work on all the rotary games. I've been lightly looking around for SARS board.
If you do find a set that are beat up these sites/links helped me clean up mine:
Thanks for the links will help out if I get a pair,missed a few on J+ last year funds were low,bit of luck someone may have some that aren't getting used
