On my 86 Capri
Vin tag on dash, 2 steel Buck tags on rad core support, metal plates under fender, door, transmission, engine block
Not positive but thought there is one on subframe?

Possibility is that your car could have had front end damage, tags changed.(as your tag has been silicone)
Or, the worst case is that someone has changed your tag as car was stolen. Usually the rivets for vin tag are called Rosebuds(look similar to a flower)
Hopefully its not!
Goodluck!
