bed rail caps?

i just put on a truxedo low pro and it does not come over the rail and left the holes on the bed rail open. i want something to put in these to cover them to keep water out and i want them to be low profile. what would these be called? and where can i find them? thanks

I also have a Truxedo and added some Bushwacker bed rail caps: They are a piece of cake to install with 3M adhesive and I think they look really good, they match the stock tailgate cover.

The problem was when I put my Truxedo back on. The caps are wider than the top of the bed so they over hang a bit into the bed, maybe 1/4". The Truxedo clamps to the bed to install so it "pushed" this overhang to the outside of the bed. They don't fit as flush as before and the adhesive has come unglued so the heat flexes them. I think If I would waited longer, maybe a few days, for the the adhesive to cure this problem would happen.

Good luck in your search.
