New Dynacorn Complete Repro Steel 'Cuda Bodies....
My bike was a "kit" bike. It came with a Certificate of Origin, I think that is what it was called, for the frame, trans & motor. Went to DMV with just the papers and they gave me a VIN. Wonder if you could do something of that nature with there body? Only trouble might be is the vehicle would be whatever year it was that you did this in, so your 1970 Cuda would be titled as a "new" car and have to pass current sniff tests, I would imagine because I know my bike had to. In AZ, when I bought the bike I had a five year period where I did not need emissions......
