Since the dash pad looks to run the full width, you could probably cut the dash all the way across, & weld the part with the VIN to the new frame-under the pad
Why ???
Just xfer the vin to the new dash, buy a pair of the special 1/8" vin pop rivets for $15 and move the vin plate. Its not illegal to do that if the vin is going back on the same car.
