If you know specifics to CA laws that would help. I've got 2 vehicles one is currently registered in State and the other isn't. Both are being merged as one. As far as VINs go just what is the vehicle? The body? The frame? Both? I haven't found a VIN on the frame. Both have VINs on the dash and on the door frame. The better body has a hacked dash so if I move the dash from one to the other have I moved the VIN as well? When I'm done I plan to take a pillaged frame & body to a scrap yard, junk yard, wherever. Will I need a title or proof of ownership for that?
