I had done one more repair that I had not documented in the blog. Part of the plastic buckle had broken and they would no longer "latch" closed. After studying the buckle's design, I fitted a piece of "springy" metal (actually a piece of a used hack saw blade) under the buckle to back up the broken plastic piece. It now works better than new.
Fortunately, the weather cleared up very nicely though the clear skies brought below freezing morning temperatures.
