I'm in this dilemma currently: I want to make wooden sides for the bed of my s10, however, the truck lacks stake pocket holes in the bedrails where they would traditionally drop in and mount. One of the guys who works at my go-to yard also has an s10 and he told me that he puts the vertical posts for his sides in between the inner edge of the bedrail and the notch-out in his bedliner near the cargo tie-downs. I was kinda thinking this: So they would be easily removable, and since I notched out the bedliner near my cargo tie-downs a little more (my heavy duty straps have bigger hooks that can be a pain to catch on the tie-down eyelets, and I have a cap that I use periodically), if I drop the vertical supports into the notched out area and they sit between the bedliner and the inner edge of the rails, and then get lumber brackets and run them into the inner edge of the rails to go around the vertical stakes to brace them, would this work? When I want to take the sides off, I just gotta loosen those brackets and then slip them up and out. I really don't feel like cutting holes into the bedrails (kinda skinny) so this seems like the best possible option unless somebody knows an alternative way that will work...
