I met Big John from SledHead Racing last week for the first time. I bought one of his roller halfs, reed spacers and some other things from him. If your looking at buying anything give him a call and ask if he has it. If he dosen't he can probably get it. He not only sells the parts, but asks questions about what you want to do with the sled, and gives you an honest answer on how to set it up. If you don't know exactly what your doing he will walk you through the process. I just though I would put a post up, because I was happy with my experience, and I know how frusterating it can be to talk with a salesman who knows nothing about the products they are selling.
