[ECONORAM]

BZP, I only did partial skirts due to the amount of corroplast I had available. I mounted a 90* steel bracket at the front and back of the wheel well, on the truck where 2 of the screws already hold a wheel well tub in place (MOPAR part). I hate dirt all over...
Anyhow, with those brackets in place, I cut a piece of 2" wide window blind to about 36.5 inches long (give or take), and drilled 1/4 or 5/16" holes at either end to match the holes in the brackets. --I remembered your work with the pvc pipe and the steel bar, so I figured corroplast wouldn't be stiff enough on its own. Punched matching holes in the corroplast and used a 1/4" plastic push-thru fastener on the front, and a 1/4" bolt on the back (had too much gap for the plastic fastener). I also cut 2" x 2" tabs every 5 or 6 inches around the arch, and plan to stick them to the truck with self-adhesive velcro strips. I only had enough for 2 tabs; had to order more from Ebay.
Weather hasn't allowed any ABA testing yet...

[edit] and when my wife finally saw them two weeks later, she was MAD as a hornet! She doesn't like any mods that detract from appearance...

[edit 2] the bolt is at the front, the plastic push-thru at the back. I forgot.
