I plan on using brass brads, available from any hardware store, and use a long drift to push the ends over, inside the headstock...
As to the VIN plate, I am going to glue my clear-coated digital photo of the VIN plate to a piece of aluminum flashing (also at hardware store) and rivet that on...It's the best I can come up with...As for official inspection, as long as the VIN on my plate matches the VIN stamped into the other side of the headstock, I don't see a problem...
