Most Popular Rack Lock for Chevrolet C/K Series Pickup

I bought this bike rack because I didn't want to have to remove my bed cover every time I wanted to take our bikes on a trip. This rack works perfect because I can roll up my cover and this thing just clamps across the bed. Taking the front tire on and off is kind of time consuming but when I travel with my brother who has a hitch mount rack, it takes him just as long to unload his bike as it takes me to unload. The wheel mounts tighten easily and the bikes appear secure during long drives, so I don't worry about them coming loose. Of course, you'll want to wrap a bike chain around the bike and rack if you plan to leave them out to make sure no one can steal the bike (although it would be missing a wheel)

Referring to special mounting instructions if you have a bed liner: (line #3). I do not have a bed liner, but I do have a molded plastic cap on my bed rails ('04 Ford F350). The first install over the plastic cap the locking pin or pin as called out in line #3 was nowhere near making contact with the metal lip of the metal bed under the plastic. What I did next on the second and final install was remove/cut away the plastic on the inside of the bed rail to allow the vertical portion of the "L" mounting bracket (Fig 4) to contact the metal bed. The locking pin is now at a position almost where it would protrude under the metal bed lip if I would remove the rest of the plastic under the horizontal portion of the "L" mounting bracket, I did not do that. After cutting a notch in the metal rail to accept the pin, the pin barely flushes out to secure the rack. A 1/4" longer pin would take care of this problem. One other thing that was not addressed in the install instructions was if you have a full size pick-up bed you are likely to attach the passenger side fork mount (Fig 2) to the right of the extension tube locking mechanism. The extension tube is a smaller diameter, so you will have resize the fork tube clamp (Fig 1) for the smaller tube. I can't explain how to do it other than it's a Chinese puzzle.
