VIN number questons

[88 hatchback]

Hey guys - So I've been doing some digging on one of my cars - as it looks like the VIN has been tampered with.... Is there anywhere on the body that the full VIN may have been recorded?

I know that the fender tags have the serial number of the car - But in order to run the car through a database - I'd need to full VIN to do it.

there are no door stickers

I'd like to hand the VIN to the local RCMP detachment - because if the car is stolen - I'd rather do the right thing.

and currently - the fender tag does NOT match the VIN plate.
