Recently moved to a state that requires front and back license plates. I have a '96 Honda civic (old but good), it did not have a front plate when I bought it. There are four pre-made holes in the front bumper, but no screws. I bought the correct sized screws/nuts and went to install the front plate but found a thick layer of foam(?) blocking me from reaching behind the front bumper and tightening the screws with the corresponding nuts.
I don't think leaving the screws without a nut is a good idea because I'm sure just the movement of driving can cause them to become loose or something. I tried googling how to install front license plates for my specific car but was told the same thing which amounted to drilling holes in my bumper. My issue is that I can't reach behind the bumper regardless. The only solution I can think of is to buy screws a size too big and force them to thread into the existing holes, but I'm hoping there's a better solution?
I shopped around a couple car places for screws. I didn't realize this earlier but at some point the screw is the right size to fit into the hole, but too big to fit through the license plate. I had a guy with a riveter help me out to a degree, we got the screws to thread through the plate and into the plastic lining the hole, but didn't quite "bite" into it snugly enough. Driving didn't bother them but a person could pull them out easily enough. Settled for using heavy-duty zip ties right now. We'll see how long those last!
