Just wanted to pay it forward to the forum and share a fix I found for GM vehicle's worn out-Doors Window channel Weather Moulding Stripping-cracking, just dried out and falling apart.
A prevalent problem for GM vehicles for many years from what I see at the salvage yard.
I didn't see anything on any known fixes for this on the forum.

Just did my friend's 2007 Chevy Monte Carlo and it looks great. Parts were only about $6.
Thought I'd share the info and pics for anyone else looking to fix the same thing on their GM vehicle to keep it going and presentable and problem free and protect the under felt window strip from the sun/elements as OEM intended.

Since the original pieces are no longer available and was cost prohibitive, the only fix I could find was this peel and stick on top good quality rubber 20mm wide x 2m e bay. It was enough to do 3 doors(have some for another vehicle) on this 2 door car.
"4M Rubber Seal Strip Car Front Rear Side Window Trim Edge Moulding Weatherstrip". I believe it is also sold in a 15mm wide as well.

I first removed any broken pieces from the window inner felt weather stripping. Tweezers came in handy for that, the ones that fell into the felt channel! Also cut off any "dangling" dried up rubber pieces.

Then I thoroughly wiped the old rubber trim surface with a rag with paint thinner, twice. Then wiped it with rubbing alcohol on a rag and let it dry.

This stuff is just peel red backing and stick on. Line up one end and stretch it out and stick in place here and there till your sure you have it where you want it.
On the Monte Carlo the OEM doesn't actually touch the window so I places it the same. It covered up and hid the old stuff's broken edge just great and is flexible and I'd say a bit thicker than the OEM stuff.

It wouldn't fit under the side mirrors so I cut it off there, hidden, it's not needed there anyway.

I'm going to do my friend's 98 Century next, it's really bad with metal rusting even. Will have to paint the rusted metal first.

Hmm well I don't see where I can post my pics here. I'll post on another forum as well.

Take care

Just want to add after over 1 year Iím very happy with the product.

I even used it on my dadís old 90 Century which had the rubber dried out and broken off on the inside side of the window.

I applied it on top of the old on all outside and inside 4 door windows.
Luckily there was just enough of the old to support the new on top.

Be sure to first thoroughly clean with a rag and rubbing alcohol UNTIL there is no more black yuck coming off the old, so the new can stick to it.

I also used in the outside of my friends 98 Century which was a challenge because the black like plastic coating was chipped down the side as well-more than the new rubber would cover/hide. So to cover that, I also applied new rubber over that lower area, butting the seam to the seam of the other-top horizontal strip.
But with the rubber lip edge pointing down.
Also then I applied some E6000 glue to the horizontal seam where the new pieces touch. I didnít have to care much about excess E6000 since it wears/blends in over time looks great after a few years.
Under the side view mirrors can be tricky but just trim as needed and you can figure it out to look very oem. Looks very nice/oem again!

I will most likely be adding this on top my good rubber on my fore van just to protect the original from sun aging.

Take care
