If you are looking for fenders, there is no source, except swap meet vendors. If you want good fiberglass, contact Fairlane Company in Michigan. They make a nice one piece front fender which fits great and installs in minutes.
actually there is a guy in Maple Valley , Washington hand making fenders, doors , quarter panels, patch panels , and more for 36's now. His name is Danny Pascoe and he does business as Creative Billet (425)433-0294 . From what I have seen, he does nice work but be prepared to pay $2,000.00 each for rear fenders and so on.... He says he will build a complete new 35-36 roadster body for $25,000.00
