The seals around the windows the 90 degree seals, shrink and crack from the sun over time.

Just a side note when trying to find a water leak. At a dealership I worked for we would set a hose on the car and let it run, well it didn't always work. We fabbed up a shower head to simulate a rain shower to give it a more real world approach to finding leaks.

It's not these that are leaking. It's the seal between the door and body. Brand new. They kink at the top rear 90 degree corner. But I did talk to someone at this past Sundays Mustang Memories car show about where to get good ones that don't do that. I saw his and we got into conversation. Some place in Ohio sells good ones that don't kink. He found them on eBay. That is where I'm going to look for replacements of my brand new ones from Latemodel Restoration Supply.

Interesting...

While judging Mustangs at our Mustang Memories car show this past Sunday, I found a Fox Mustang that had perfect door seals. They did not kink like mine at the top, rear, 90 degree bend. I'm very dissappointed about these brand new door seals I bought from Latemodel Restoration Supply. It's the kink that's causing all the problem.

I try to buy most of my replacement parts from my local Ford dealership. Many parts are still available and the quality is never a concern.

Yeah, I think that I'll go that route.
