I got my parts from excelhobby, they ship from NY and quick, got to FL in 2 days, even before they took payment out of my account! Here is the link: http://www.excelhobby.com/excel_hobby_001.htm

Good luck, by the way, I wouldn't spend too much money on the smartech, its a good buggy to start off with but I soon saw how they really don't compare to some other buggies out there. For bashing around the yard, they're great. Not for the track though.
