L-shaped rubber finishers where sills meet front wheel-arches
 

I'm looking for a pair (LH and RH) of those L-shaped rubber finishers that are located at the base of the front wheel-arches, where the wheel-arches meet the sills and the bottoms of the front wings.

I would also need the six screws (three on each rubber finisher) that attach them to the wheel-arches.

If you're not sure what I'm referring to, this link to a Rimmer Bros diagram shows the parts. They are listed as item no. 12:
