I spent the afternoon installing the working replacement clock and ran into some interesting finds.
1) original clock doesn't work
2) original clock is deep fried
3) Portions of the printed dash circuit relating to the aforementioned deep fried clock are melted.

Here's some photos. I am constantly thanking my grandfather Simon for buying all the factory repair manuals for this car back in 1971. It listed the steps taken and fasteners that needed to be removed to get the dash pad out and then the lower gauge cluster. Very informative in terms of instructions! Compare that to the similar vintage Mopar manuals which would say something like: Step 1: Open car door. Step 2: Remove gauges. Step 3: Repair gauges. Step 4: Reverse procedure. Step 5: Close car door.

Once I got the original clock out and saw that it was toasted, I temporarily installed the new clock but it was not getting any power. So I pulled the entire gauge pod and found out that the printed circuit was melted in at least three places along the "hot" route to the clock. It is nice of Ford to list their part numbers on everything on this car. Very helpful: D0VF-10C956. Of course there aren't any out there but I'll start looking anyway. I did see a guy selling the entire dash instrument panel for $1,400 on ebay. LOL. When I looked at the close ups I could see similar burn marks on his printed circuit as well.

My solution was to disconnect the original bad clock terminal ends on the printed circuit and cover them with electrical tape. I then routed a hot wire and a ground wire from the gauge terminals to the fuse box and the dash frame, and the clock immediately started running and keeping accurate time, clicking every 55.7 seconds to rewind. While I was in there I checked all the dash bulbs and miraculously, they were all still good.
