I took the door panel off the passenger side door because one of the metal snaps was out of position. It was threatening to puncture a hole in my door panels, which are in surprisingly good condition for a Texas and California car. It was interesting because: The door panel had dates that matched the time the car was built. I thought they looked a bit too fancy for a Ranchero, even a Squire. But I guess they must be the ones the car was built with. Not something off a Mark IV. They are the color of natural leather. There was a piece of thin tar paper protecting the door panel that was taped to the door. It took some damage today, though. There was a circle at the bottom front of the door with four screw holes for a 6 inch or 5 1/4 inch door speaker. The tar paper had a perforation shaped like a square where the speaker would go. I was surprised at this because I don't believe any radio was offered in 73 Rancheros that used door speakers. Perhaps the doors and door panels were also for a Torino. I noticed some two piece speakers on Ebay. The tweeter is small and the main speaker is 5 1/4 or 6 inches. They come with a detached crossover box. I think it would be cool to put the tweeter in the same location in the dash that the later Rancheros with 8 Tracks and Cassettes had. The little tiny speakers that had not grills per se. Just a group of concentric circles drilled in the metal of the dash. I hesitate to add speakers to the doors since it would involve cutting my door panels. I don't like modern speakers because they are 4 ohms , not 8 ohms like they used with the factory radio and I like to use factory radios. I DO like the fact that modern speakers are plastic, water resistant, and generally have good sound. I don't like old speakers because they tend to be made of paper and are damaged by sun on the rear shelf and water in the doors. But, if I could find the proper GRILLS for the door speakers, I might try them anyway. I would also try to find modern water shields for door speakers. They look like a bowl of foam that you screw behind the speaker. Anyone know about grills for the doors? I would never use the grills that come with most modern speakers that look like a space ship and don't actually protect the speaker from objects or the sun because. I would want grills that look invisible from a distance of a few feet away.
