I was looking at ladder racks on usrack.com and came to the conclusion that for a bout 60 bucks I can build a $399.00 rack! Im looking at building the individual racks that go in the front and rear of the bed. Mostly for hauling canoes. I know I can rig up a bolt for the stake pocket but I need to make a clamp for the other end of the angle iron. Im going to use about 16" of angle on each leg. Anybody got any designs of clamps that will go underneath the bed rail to clamp?
