I promised you guys pictures of my attachments, and I have finally delivered a write up on my wheel skirt attachment... I made some clips (from scrap metal banding that holds pallets of big plastic pipe together) in shape of a "U" with a 90* bend, and drilled a 9/32" hole on the flange(for a 1/4" rivet), and attached them to the fender lip with epoxy... For reinforcement, I used a 36" carpet bar, with holes drilled in for the rivets...
I attached the carpet bar to the inside of the bumper cover and rocker panel cover with one wood screw at each end, for easy removal in case of a flat tire...
I then cut a 20x36" sheet of coroplast to the shape and made mounting holes(it took a couple tries) and used my 1/4" nylon rivets to attach the skirts...
I need to make some more mounts, and cut new panels out, the pictured one contacted the tire due to a failed mount and rubbed a hole... But, regardless of how it looks, they work great... After I drilled the holes in the mounts a size larger, and added a hole in the carpet bar for additional riveting, they're stable(no vibration), and the rivets are easily removed with a flat screwdriver/installed with thumb...
Best part about this mod, is so far, it's cost me only $25...
