I was surprised at how much duct tape AMC used in the production of there automobiles.  Here is what I found.
As you can see they used duct tape to hold the Back-up Light Switch wire down in two places.  The first place it is held down is just as it is coming out of the floor.  The second place is under the accelerator pedal.
I also found duct tape holding the carpet together by the High Beam switch.
This piece of Duct Tape was found under the rear seat on the drivers side of the car, it is covering the frame access hole.  For some reason this Machine and my other Machine had duct tape only on the drivers side of the car under the rear seat.
