those fasteners are difficult...i have them and I used epoxy on the deck holes...also use a small screw driver to get them apart and a tap hammer to set them together...not too bad if you do it that way when installing and removing your dodger...also used Sikaflew to bed the fasteners to make them water tight...no leaks yet
