Attached is a picture of an untouched vent window frame assemblies. I peeled back the division bar felt so that I could see the tabs from the rubber seal around the vent glass. I don't understand why Ford placed elongated holes/slots in the division bar, when the tabs from the rubber seal only fold over the Stainless-steel channel, not through the division bar.
So, why do both of these pieces of metal have slots, when the tabs only fold over one of the two?
