I'm looking to remove the splash shields to inspect metal condition behind them on my '65. I started on the right rear one, and found two screws that I removed but still can't get them to budge. How many screws are there? I do see what looks like a third screw, but its the threaded end. Could the screw have been put in from the opposite side at the factory? I don't know that this fender has ever been off, I know it hasn't in the 25 years I've owned the car. Is there more than three screws? Should it come out pretty easy after I get the third one that I see out?
