Now that I have the sound deadening off of the floor under the seat, I have discovered a few things that I am wondering why they are there.
1. As shown in Beans' photo of the floor of the car (in my 70s GM build quality topic), there is a 4" (or so) hole, covered by a plate that is held in place by the sound deadening. There is one on each side of the car.
2. Just behind the hole above is a much smaller hole with a grommet. There is also one of each of these on each side of the car.
3. On the (US) driver side, there is a 2" x 4" (or so) plastic tag that is attached by a wire loop to a small plate near the base of the seat. The wire goes under the plate and is clamped in place by bolts from the outside of the car. I can't see anything written on the tag, but one side of the tag is painted in the body color.
What are the purpose of these things?
