Truckrolet,
Brian knows waaay more than most people about NAPCO's. We refer to our trucks as NAPCO's, whether factory or dealer installed, so people understand it is a 4x4 with correct running gear. NAPCO provided the factory with the kit.

Brian,
I found that adding a plastic or metal washer helps a great deal. You could add a little grease between the washer and the bolt to aid in the bolt head sliding over the washer as it spins. I did this with the inner fender to fender bolts and it worked really well. I plan on doing it with the bed as well.
