Topic: Vent window seal tabs

[Angela]

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?

Likely a design or engineering standard Ford people used aas a standard for the specific part not the application.

Another would be the "drain" holes in the Mustang floor pans. No purpose for them on a Mustang (designed to allow the primer to flow out of the interior of the car if the bodies would have been dipped originally like other lines (T birds for example) but they were included in the design likely IMHO because that is what they did on all floor pans

Good thought Jeff. So are you in agreement that the tabs indeed only fold over the stainless piece, as I see in the picture of the original frame?

Looks like the raised rolled corners and holes in the division bar allow the two to mate properly, and keep the tabs below the base of the channel. 

If the tabs fit over both, the tabs would appear to push against the the runner, forcing it "up", making wear points as the glass went up and down?

Exaggerated not-to-scale view of the setup keeping the tabs lower than the seal/runner.

Wow, good thought.. thanks for the drawing. I think your explanation makes sense, meaning the slots exist in the division bar so that there's room for the tabs.  Cool. I had been thinking that the original frame I took the picture of was assembled wrong, but I now thing it's probably correct: tabs bent over inside the slots in the division bar. Thanks for your help!
