Vent Window Seals. . . Help!

[Super_Dave]

Okay, I purchased a rebuilt set of vent windows form a member for my '74 build that is nearing completion. They looked great (new rubber, hardware, powder coated...).

So we are trying to get the vents installed and we are having one hell of a time. The seals do not want to fit correctly and the frames do not want to fit correctly.

I have looked over the seals and something is off about them. I purchased these in lieu of rebuilding mine because the price was right and it would save a lot of time.

As best I can tell, the weather seal doesn't look to be correct. It almost looks like a universal seal or maybe even the wrong year or something.

The outer lower portion of the weather seal, when the vent is closed, gets pushed inside the truck and pulls away from the door, creating a huge opening for water to run straight into the door and the cab!

What the photos don't show because the vents are closed, is that the outer lip of the seal is the same height as the inner lip and they are completely smooth... no indentation or change in the profile whatsoever. It's that thin outer lip that is getting pulled inside the door when the wing closes.

The lips are very thin and nothing like what the online images show or the old one I pulled out. The profile of the weather seal doesn't look anything like other seals online or like my old one. . .

The passenger side is terrible. The drivers side does the same thing but not nearly as bad. My old seals worked like they should; were just old and needed replacing.

Now I may be doing something terribly wrong but I don't believe that to be the case. Input is seriously needed!

I will upload photos of the Passenger and Drivers vents, then images of the others online and finally my old one. It may take a second post, but you will see what I mean.

Educate me, I need it!
