due to repeated removing and reinstalling when washing the truck (water leaks out if I don't causing streaks) I have blown out the plastic in the tie down anchors. these are the ones by the bed caps, six of, black plastic. Ford wants $60 @ for them. I have contacted all the wrecking yards around here with no luck. I know billet used to make a s.s. filler replacement but no longer does. Any suggestions ?
