RE: 17mm hub conversion????
get 17mm hex hubs for a 1/8 buggy on the LST2, and if it has a 3mm pin, drill it out. those are the only instructions:P
as far as the X...you can't do the 17mm hub conversion if you have the right AND left handed threads on it. with the Tsais CVD's, if they're all right-hand threads, you can use the cheap 17mm hubs that come w/the X and XSS
