The removable rear window weatherstrip on my '69 had sheet metal screws in the upper corners (4 each side) that were driven through the rubber into the fiberglass step that's above the actual sealing surface, and I can't find any mention of them in the AIM. Has anyone else seen this? Looks like someone's "quick fix" to me.

That is factory. Makes it really easy to install a new seal.

they look like factory screws

If you look carefully at the new seal you will see holes for the screws. They look like they were just randomly placed in the fiberglass but were done with some kind of template. Really makes it easy to "hang' the new seal. Once you get it in and all lined up, install the window to hold it compressed in place for a few days until everything sets up and cures.

Hi,
I agree that it appears St.Louis was installing the screws.
But now and then someone reports that their car doesn't have the holes in the fiberglass so didn't originally have the screws.
I don't know if it was hit and miss or if at some times screws weren't being used???

If that work (or lack, thereof) was hidden by the time the car was complete, no one would be the wiser and someone would have done less work (and therefore 'faster') than expected. Done a LOT at all US auto factories in the '70s. The "Mark of Excellence" sticker put on GM cars was just that....a sticker.

When I replaced my window weatherstrip it did not have the screws and I could not find the holes under the weather strip. It has them now, probably not in the "template" place but there anyway. It makes installation much easier.

Great pictures as usual Alan.

BTW; what do you use to get that factory zinc chromate primer appearance? I just bought some of this (pictured) but, it hasn't arrived yet and I don't know what it'll look like when applied.

Thanks,

Hi Doug,
In the early 90s when my car was apart there was still a little Rust-oleum
zinc chromate primer around.
I had 1 can of it which matched the color of the primer used on the birdcage on my 71… a somewhat mustard green.
I didn't know that folks working on airplanes had sources for the zinc chromate paint.

Various Corvette parts suppliers were selling a birdcage paint that was more of an army green and matched the primer that it appears was used on mid-year cars. It didn't match what was on my car.

I had the local auto paint store mix up a pint of enamel that matched the mustard green.
So I used the Rust-oleum and the mixed enamel.

Only time will tell if the paint you have coming is going to be similar to what's on your car.
Regards,
Alan

Just a quick note in regards to that primer color. Dupont Vari-Prime is very similar to that color. It's an etching epoxy primer. Not cheap. 1 quart plus activator is over $150.
