Ah I see, well there arent usually very many 3 wheelers around here for sale/part but when they do come up they are fairly cheap so I'll deffinately keep an eye out. Could also join a tecate forum if you havent already and see if theres any good deals on parts.
Should be a pretty sweet set up though when its all said and done, even though I've never been a big 3 wheeler fan, I had an atc70 at one poin in my life so I can appericate it
