I recently bought a 2014 Silverado 1500 and it came with the factory bed liner installed. Apparently when the dealer put the bed liner in the truck (before I bought it) they cut out 9 holes around the tie downs around the top of the bed. I do not plan on installing any tie down hooks at this time so I was hoping to find some plugs to seal off the holes.

Does anyone know where I can find the plugs for these 3 1/2" holes?
