I know it sounds stupid but my car was stolen at one point before I owned it. I was told on an IROC the VIN is in more than one spot but I cant recall where I was told it was at. Mine at the windshield was removed so I'm starting from there. FYI it's a 1988 IROC Thanks

 

there are nine places where the vin can be located. One was on the dash but u said it was removed, another is on the fire wall, right behind the gas tank. there are few other places that I cant remember but those are the three that I can think of right now. I would go to dnv website or do a search of vin number locations on a car that should help you out the most. Let us know1

 

Part of the Engine ID has the last digits of the VIN in it.
