OK, here's what I'm thinking on the bumper. No scoops, spoilers or bug deflectors (sorry, Chip).
Looking at the blue truck example photos I have, it would appear the builder raised the bumper which likely entails cutting up the frame horns and other mods I'm not willing to do. Sooooo.... I think a more modest knockoff is in the works.
I picked up some 18ga. sheetmetal strips from the metal store this morning and made a couple of patterns to see what might work for me. A 1" wide strip with 3/16" folded back on one side and a 9/16" right angle on the other side will lay into the grille shell and follow the angle of the top of the bumper. I'll have to trim the bumper edge to match the new pieces and end up with a 1/4" gap. The edge of the bumper is somewhat irregular, so trimming it will get rid of the bugly.
More to come...
