67 Barracuda bench seat with fold down armrest
Well, not so dumb after all. The original armrest screw was 5/16-18 and was a shoulder bolt. Apparently when I put the bumper bolt on one side a couple of decades ago, I drilled and tapped the armrest on that side for the larger bolt. Anyway, for now I just put a new 3/8 - 16 cap screw on that side, left the original on the other side. If I have any trouble with the new bolt loosening, I'll look for a shoulder bolt in that size.
