Had the opportunity to search for the 68 AM/FM stereo radio and parts from a Metechun built 68 Mustang J Code 4psd convertible. Having never seen this option before and being one of the rarer 68 Mustangs options (only 4701 installed out of 300+k cars), thought I would share pictures of the radio, harness (unfortunately cut at the speakers) and door speaker location. From the door picture I would assume that when ordering the AM/FM option Ford used the deluxe door with courtesy light cutout (taped over), separately cut the oblong hole for the speaker and installed the deluxe door grilles.
