I keep breaking my rollers on my 60" Lazer Z. I think that I have broke four bolts this year. Can anybody tell me where to by new bolts, hardware, etc.. My dealer makes his own kit and wants to sell me everything including the wheels when all I need is the bolt, or maybe the nut. He charged me something like 21 bucks for his kit. Any ideas? Also, the wheels are in the second to bottom hole in the deck. Where do you guys have yours at?
