Id definitely look into getting some sort of hub conversion.. If you pay to have a custom set of wheels made, and something happens, you'll be in the same boat your in now.. If ya come up with a way to convert the hubs to generic 2.2 or whatever, you'll have a vast selection of wheels to choose from! I saw in the back of a RC magazine, there was an ad for custom rc machine work.. The site was http://www.stlcustomhobbies.com/If ya have the money and time, maybe look into that? Best of luck and be sure and take lots of pix if ya start modding it!! Everyone loves a good mod story!!
