The VIN plate on a early 90's Ford Escort is riveted the the plastic dash defroster trim panel. You just pop it out with screwdriver if you want to swap VIN tags. I noticed that when working at Ford dealer when the cars were new, seemed laughable. Although they also had VIN stickers on sheet metal panels.
I bought a 91 Eagle Talon with the VIN swapped dash defroster panel. It didn't match the door sticker or other body stickers. Parts car it is.
