Nope, didn't start life as a performance model anyway. Was originally the previous owner's grandfather's car and started out as a 270 so no big deal on the missing fender tag. I was primarily interested in the build date so I'd know when to celebrate it's "birthday".
I'll get busy and start pulling seats looking for the broadcast sheet but don't have much hope in finding them because the PO put new carpet in the car.
Thanks for the info, everyone!
