I did not find the 04302 basic part number in the text section of the 65-72 L-M MPC, so I went to the diagram and noticed that the number we should be using (for the Cougar) is 04774. Refer to picture #1
Part number 04774 was not used on 67-68 or 71 & up, it was only on 69-70 Cougars. There are "without radio" and "with radio" groups for each of the two years. Refer to picture #2
I went back to the equivalent Ford MPC - refer to pictures 3 & 4. The Mustang listing is much simpler - black vs. light teak vs. dark teak, then with or without radio. The Cougar had a wood grain version, but for standard interior the part was color keyed and therefore the MPC has a lot more individual part numbers comparatively speaking.
Unfortunately this is a case where the number cast into the part does not help us identify the service part number.
