I need some nice looking bed caps for my 2003 supercab truck the bed caps need to have those little tabs that you can pop out and put them back in.

 

yup

 

Are you talking about the plastic bed rail caps that come on the truck or are you looking for aftermarket caps that bolt on over those for added protection?

 

the bed rails itself and those little bed caps that snap in the bed rails mine look really rough

 

There are a couple of companies that make aftermarket ones. Try Google, as I can't remember their names right now.

From what I have read, however, none of them fit or look as good as the OEM ones. I replaced the tailgate cap with a Ford one and it was around 90 bucks Canadian so the rails won't be cheap. A lot of guys here just sand them and paint them too if they look a little scabby.
