I 2nd Eric Vaughn in Monrovia. His dies are the perfect shape. You'll probably wait quite awhile to get it done though…just saying'.
check with troy ladd at hollywood hot rods, lucky burton at lucky's hot rods in burbank or Jack Fields at Starlite in Torrance
While in Upland prior to the LA Roadster show we visited RPC Fabrication & Speed. Address-1308 West 9th St. Bldg. A. Phone 909-981-0336. They had a louvering press & a variety of dies. I also noticed that he also had a swap meet place at the LA Roadster Show.
