I bought the bike fork mounts that go right into the front track behind the cab with a couple unistrut nuts. But bcause I have a headache rack and a toolbox in my bed, I can't use the front track like is shown in all the pictures. I had them installed on the side tracks, and the bikes got loaded sideways in the bed, which worked fine until my wife got a new bike. Now she has a recumbent which is far too long to go sideways. The only track available to mount to is the bottom track as the bike has to go length wise in the bed. I tried putting a single bolt through the fork mounts, added a couple fender washers so it's bolted to the track not the bed, and tightened it down. It doesn't seem nearly as secure as having it bolted in place with 2 bolts did. Even nice and tight it still wants to rotate around which leaves tons of opportunity for those fender washers to move and possibly fall out of position. Does anyone have a solution to getting a bike mount on that bottom track? Only thing I can think of is to bolt a pressure treated 2x4 between the two bottom tracks and secure the mounts to that. I'd like something a little cleaner looking if possible though.
