Convertible rear window fix 1966 Polara 500

[xxcarguy]

So has anyone ever had to fix a window like this? It seems a lot of replacement tops look like this. Is this a zipper location problem or does it just need to sit out in the heat and conform to its normal shape!
Thanks for your responses.

Can't hurt to park it outside in the bright sun and 90*F temperatures. Easiest thing to do.

I was thinking that most top manufacturers offered the option of a hinged-in-the-middle "hard" rear window?

Enjoy!

Can’t personally say anything about replacement options out there, but I replaced my deteriorated rear window with heavy duty (cold and UV resistant) marine vinyl. I cut it to size and sewed it to the existing vinyl where it zips to the rest of the top.

The one in the picture most likely just has too much material, the original one that I pulled from my car was pulled taught and difficult to unzip, my DIY replacement is about the same, and it doesn’t sag like the pictures.

Depending on how much it sags/wrinkles you could try and use a heat gun on it, though it may make it worse if not done carefully.
