I know there are other places to ask, but I feel like I know you folks. Also, I have tried and they tell me "you're doing it wrong" Okaaaay. But I followed the directions that are supposed to be doing it right.

I have a 1980 911SC with the rubber windshield trim. I got the trim and seal from Pelican and a new windshield from Stoddard. I used the cord method to install the glass and got all of the rubber around the pinch weld. However the rubber doesn't fill out the lower corners on the outside. There have always been gaps on each lower corner. I bought a book about 911s before purchase and it lists this as a design flaw. It wasn't a great book, but I think the corner issue is a common problem.
Now the rubber has worked back out and over the pinch weld at the lower left corner and I can see that the glass is thinking of jumping ship. I may be able to recover the rubber lip back over the metal, but I only have a few miles on the new glass.

Do a search on pelican. There are a couple windshield threads with lots of good tips.
My tip is to make sure you use Porsche rubber seals and not aftermarket. Window glass rubber is one place where Porsche brand is superior.
I’ve also seen installers “fit” the aluminum trim to the corner radius with a wood paint stick. Porsche factory install used some adhesive at the corners.
But the pelican thread covers a lot of ground. (IMG:style_emoticons/default/beerchug.gif)

Installed a few 911, 356, Type 3 etc windshields. If you keep the alum trim, it is super tricky to get right. Honestly, I've never done an install with the trim where I walked away happy. The BEST option I've seen is take it to a shop that specializes in these types of seals. Lots of old muscle cars and trucks use similar. Letting someone do the install that's done it 100+ times already will pay off.

you must use the original german seal not the reproduction and make sure that the trim is firmly embedded in the seal, then load with weed wacker wire and pull into place

Windshield on a bench where it can hang over the edge on three sides, rubber on glass, aluminum trim into rubber( needs to fit reasonably well not all twisted from removal), rope into rubber, soapy water on rope and rubber. Very helpful to have a friend or two to keep pressure on the outside while pulling the rope. Once the seal is over the pinchweld keep pressure and massage the glass back and forth. Sometimes I roll up some butyl to put in the corners on the outside where the rubber doesn't fit the body. As said before certain aftermarket seals make this job much more difficult!!!

The old timer Porsche body specialist I knew put 3M 'dumdum' weather seal strips in the lower corners (on 911s) to fill the gap outside the seal
