well you can go to So-Cal speed shop
http://www.so-calspeedshop.com/ but most likely too much $$ and will take long. You can go to Walden Speed Shop
http://www.waldenspeedshop.com/ They can do anything when it comes to metal, but i dont think they have done a mini tub. And there is Hot Rods and Custom Stuff in (sp) escondido. That is the first three I can think of.
