Very nice story Roger! I knew an old fella whom restored Corvettes and he told me a long time ago about that said plug and apparently they were popular for falling out. He had pictures of a 63 split window that had burnt due to that plug falling out. He had pics of the burnt hull all the way through the resto process to a finished product. Looking at those old pics was too cool to me. You won't see that now as he has passed on. Anyway, cool story. Some of us didn't grow up when these cars were a common occurance on the road ways.
