I was/am in the market for some 4 & 1/2ft bed rails to fit my truck with my tool box. They guy at the shop said he couldnt mount them in the center of my bed caps because there was nothing to screw into other than the plastic bed caps??? Ive seen many trucks with them on there and know it can be done so I was wondering if anyone who has installed them knows somethin me and this guy dont know. The bed rails that I was looking at are the round stainless steel and dont have the "foots" on them and looks simple but my truck has a bedliner and I can see his point. Any help is appreciated... Thanks in advance.
