Installed the mud flaps today, a total PIA. 
Fronts were fine getting access to screws but the problem was that on each side one screw would not tighten. I tried everthing I possible could to get the screw to engage but it just would not. If I took of the flap the screw went in and tightened no problem.
Back is a royal PIA, even a stuby screwdriver didn't work, I had to use a screwdriver bit with a wrench to get screws off. And again, one screw on each side would NOT engage with the flaps on.
My guess is that for some reason it is just too short with flap on to fully grip the thread.
I even took my time to wax the area being covered but the frustration of the screws not fully going in killed me and wasted about two extra hours. Going to have to try and find some longer screws that match.
