When I was building the 27 roadster I joined a bunch of different sites related to these kind of projects. The hamb, killbillet and rat rods rule are the only ones that comes to mind. I will remember the other names later and post them. Be prepared if you join, there are alot of guys that will point out every mistake on your project. Some guys have turned rat rods into an art form and dont care about what the term actually means.
