There was only one original radio speaker.....in the dash between the defroster vents. Finding the dimmer switch on the floor reminds me of a story a friend from work told about his 10 year old daughter. He had bought a jeep and was taking her for a ride when she asked, "Daddy, where is the switch to roll down the windows?" She had never seen a car without electric windows.
It is amazing the things that were luxuries to us are now considered standard.
