Want To Buy/Ultimarc Trackball Rebuild Kit.

[thewildace]

   I'm wondering if someone here can help me find the parts I need for my three inch Ultimarc trackball, which I use in my arcade cabinet? It's been having a real annoying issue lately, and the ball bumps & bounces like crazy whenever I move it in a direction, towards the right. I can tell the ball is fine, as it's okay if I move it away from that side. I did take it apart to clean everything, but the problem persists. I'd need a rebuild kit, consisting of the three rollers & six bearings, and hope someone here has some extras they can sell. Would I be able to buy the Happ (or any other generic trackball) parts to this, or does it have to be Ultimarc brand? Thanks in advance for any help.
