I have to have a certified VIN check here. Any car coming from out of state must go through this before it can be licensed here.
If I can find the chassis ID number and it checks out it can then be licensed easily, possibly as the year of the frame, the SPCNS means nothing to them other than identifying the body make and type.
Both my '65 Cobra and the '33 Vicky were originally built and licensed in AZ where we were living at the time, the Cobra as a '65 Ford Shelby roadster and the Vicky as a '33 Ford sedan, when we moved back to WA I had no problem registering them there or when we moved here. Neither car had an original frame or vin tag, the Cobra only had the NAF ID #, it was very easy in AZ, had to go through a pretty thorough safety check with both cars, then took the paperwork down to DMV to get titles and historic plates. Funny thing about the Cobra when I went into license it after the CO vin check, the clerk couldn't find ''65 Ford Shelby Roadster'' in her database...
Colorado DMV has always made it difficult to license vehicles such as street rods, way to many hoops to jump through, fees to pay, etc..
