1969 rear license plate mounting question
I know this seems like a trivial question but I'm trying to get things correct on this car. I went to put the rear license plate on and the square plastic/nylon fasteners are too small for the holes on the car.
The square holes on the car measure 7/16" and after going to 3 different auto parts stores I found the largest ones made are for a 3/8" square hole. I tried to used the 3/8" piece in the hole thinking that if I run a screw through it, it will flare out enough to hold it in place. It did not work and the plastic piece spins around in the hole.
So did they make larger inserts for these cars back in 69?
Or I wonder if the rear panel was replaced and the aftermarket panel has holes that are too large?
Any thoughts? I really did not want to use a bolt and nut on it, I wanted factory original set up if possible.
