vin tag lost at paint help

I wish i coulda sopped payment but i had already paid the man when i picked the car up but didn't realize that the tag was wrong till one night putting my car back together that i just by dumb luck i noticed the vin number didn't start out with my Lm23 numbers an after finding this i calls the guy up an told him about it an he's like i thought that was your fender tag but if its not i don't know what coulda happen to it... needless to say i still ain't happy about him loosing it an then trying to cover it by placing someone else's tag on it.
Good chance your tag is on a Charger...
