I was tempted to point that out, too, but I didn't want to start another debate about wonderlinks/missing links etc vs re-using pins. I, too, have been riding almost half a century and I had no idea these connecting links existed until this past year. Now I'm afraid to ever use my expensive chain tools ever again.
