Several years ago I bought a 67 Crown 4-door for parts from a salvage yard, though this car only had the AM radio, it had the complete compliment of speakers, which was hard for me to understand. I did think that the installation of the door speakers on the 67 was a more professional looking arrangement than the 68, which sort of look like an after thought, though they work well. I also have a 68 Crown 4-door that has the AM/FM Radio and Tape Player, it also has the small box speakers.
