Just a little rare part trivia......the very last of the '81s and probably some of the very early 82's had a carpeted section under the dash by the steering wheel. It attached to two existing bolt holes on the interior steering mount and had tabs that allowed it to slip up under the lower dash edge, was designed to hide the under dash wiring and clean everything up down there. It was about 20" wide, and was notched at the driver's end to go around the delay wiper module.
When Chrysler changed the delay wiper module, this carpet-on-cardboard part vanished forever. I had a '81 Aries Custom coupe that was built in June of '81 that I stripped last summer and it had this part on it. Plan to put it in my '82 SS eventually, had to enlarge the notch to clear the wiper module.
