You can use the advanced search function on IPDB.org and search by boardset if you're not sure which will fit your game. I can also alter boardset configurations upon request to suit a particular machine. (May involve a higher or lower price depending on what elements need to be changed to suit your machine)
Feel free to ask any questions in a PM.
