Well, I didn't know if you meant for your '92 or not... . A nice, black mudflap would look nice under there, with a small SS trim piece on the bottom, IMO. It'd be easier to attach, and a little more forgiving, should you hit something on the highway.
I didn't think to mention, don't use a soft rubber flap. The SS tip may flip up and tap the cab... be sure to use an anti-sail mat, if you go that way. You can cut out a nice one with a little jig-saw.....
