just a couple comments/suggestions:
the factory never used clear silicone to hold any window glass in the channel; if found, this suggests a previous repair by ???
the rubber strip or glass setting tape is what was used from the factory on all windows.
an easier way to install the channel is to place the tape over the glass edge, place the channel, centered, over the tape, and use a rubber mallet to drive the channel onto the glass. Place the bottom glass edge on carpeting or other soft surface before installing.
if should not be necceasry to "tighten" the crimp in the channel with pliers, once installed on the glass. This suggests to me a bad/weak channel in the first place, and could cause the glass to break.
Excellent write-up and excellent pictures.
