You should be able to source a suitable belt and wheel from a power transmission manufacturer (check yellow pages in your city for listings for companies that sell toothed belts, they can advise you on a suitable unit).
Finding LXD55/75 motors is the hard part. I can tell you that Bill Vorce (telescope warehouse in the States) doesn't have any at present as I was in contact with him the other day regarding their availability as I need one to fix an LXD55 mount. He does have the 497 Autostar with DS motor kit for around $150 USD plus shipping (look for scopehead on eBay).
Custom made worm wheels cost a flipping bomb out here unless you know someone who's got a lathe, indexing head and a lot of patience! Bill Vorce has genuine Byers worm/wheel sets from around 500 USD, or there's Beacon Hill Telescopes in the UK that can supply a suitable unit. There are alternatives such as various friction drives that are cheaper to implement.
