So here is one side of it done. I ended up just cutting the top off one of those strip washers. Also needed to cut some access holes so for the front mount to get to back side of bolts, holesaw cut through sheet metal easily. On back of bed there was access already. I'll show some pics soon with things on my new ,roofrack for my bed mainly it will be for RTT or is it a bed top tent now?
Btw look at all the gunk underneath bedliner, never imagined so much debris would get up underneath there. In a few spots it's already worn through paint. Wonder if getting rid of the plastic and linexing would be better.
