that is a real bummer man.. dont worry, im sure there are a ton out there somewhere but also just think about saving a little more and buying a fresh new kit that no body has tampered with yet.. i have gotten cars in trades or sales that i end up having to put more money into to get rid of all the slop and play that the parts have developed from use and abuse. its worth it to save the extra and buy a new kit. xrs or x11 they are both really great kits and the xrs is fully upgradable to an x10 or x11 when your budget allows.
