My state would never check the frame. The lady walked out, saw my glove box vin and signed me off.
My state does on out of state titles...hence the issue if you ever sold a vehicle with an aftermarket frame and they tried to title it in another state.
How does this work if you are in possession of the tile and original frame and you want to upgrade to a new TDK or KE chassis? Can you have the numbers stamped into the new frame? Or do you have to graft the original stamped VIN into the new frame?
The KE frames have their manufacturer serial number on them and they will not adapt your VIN in any way. They generally give you a manufacturer certificate of origin with their frame number and you save that.
Best way is to have the title for current VIN in hand with it registered/inspected. Then you do the frame swap, you show them the manufacturer certificate of origin for the frame at DPS, and they correct the title under the existing 66-77 VIN to include the new manufacturer frame serial #/VIN.
People replace frames from collisions so there is a process but some states are stricter than others with much more scrutiny. Depends what your state considers as the VIN per the title.
