That's a later tag.
You could get in trouble making out of thin air!! If they check for hidden VIN you'll have an 0 **** moment. I don't if or where hidden VIN is. Check under back seat for build sheet and if Shop order match fender tag you could get away with a made tag. 65 tags were spot welded on. If you rivet it on, only if asked about being riveted say welds rusted and it was loose. Doubt they'd ask.
