The gen 3 Sable antenna base was correctly guessed in the second comment, by Frank. I wouldn’t have had a clue if I was trying to guess that. Here’s what seems to be happening more and more: as our readership grows, there’s at least one (or more) of you out there who is intimately familiar with every detail of any given car. Like the little piece of trim on the ’65 Sports Fury that tiredoldmechanic had replaced on his ’65 Sports Fury. It’s a bit scary, and it means we have to work harder than ever to stump you. I suspect I probably haven’t worked hard enough with this.
