I am in the process of installing the FFR sun visors on my Mark IV and have run into an issue. It appears as if the FFR supplied screws that attach the mount clips to the windshield frame are a different size/pitch than the tapped threads in the frame. I tried to measure the FFR supplied screws using a pitch gauge and it looks like they are 8-32. The threads in the frame "look" finer but the hole is too small to measure them. Also, no idea if the tapped holes are standard or metric thread.

Anyone else run into this?
