I talked with original owner "Rick" again today. He confirmed that the oil filter in the photos is the oil filter he put on in the late 1970's or early 1980s. He only used factory parts to maintain the car. I sent him the link to the SD455 Registry and he was surprised that they built so many 73 Formulas with the SD455. He thought there were only a handful so the 43 total number came as somewhat of a surprise.

This evening I used a flashlight and an inspection mirror to look under all the seats and did not see any signs of a broadcast in the springs or on the floor. I pulled the spare tire out and used the mirror to look behind the cardboard bulkhead liner and did not see anything in there either. I don't want to needlessly pull that back seat since the bottom cushions are so hard to remove and replace without damaging the vinyl.
