This is a big No No in Kalifornia now from what I've read. It's called washing the title. Alot of custom shops got busted for it. Mostly by registering their non original street rods as the original body year in states that register by body year design. Basically buy a 32 ford roadster kit, and register it as a 32 roadster, not a special build for the year put together. They do this to get around emission requirements. And to wash salvage from the title. I read Boyd Coddington and some other big names got busted for this a year or so ago.
