wavy gasket?

[Granny's Duster]

Hey guys, I need some help. I'm installing a new rear windshield gasket in my 75 Duster. I have the gasket and windshield in, but the gasket is not sitting as flat in the lower corner as I think it should. I removed the lockstrip and tried to move and shift the gasket a little. On the inside the gasket is wavy. Any suggestions?

Third picture down... Is there a part of the gasket that isn't in in the upper corner or does it just look that way?

Could be that there is too much sealant between gasket and body. The glass is suppossed to be a little samller than the body opening. The gasket has approx' 1/8 inch center web that is supposed to be squarly between the body ( edge of pinch weld ) and the glass.
If the glass doesn't seat low enough the gasket has to roll outward at the top.
If you used a sealnt that will soften with heat you might heat it up and shift the glass downward and inward.
By shifting the glass, even climbing up there and sitting on it imediately at install I got all of the top of my notchback rear glass and gasket to seat right except for one place about 6 inches long at the right upper corner. Yes a good bit of my sealnt oozed out.
Weeks later and sitting in the hot sun it has settled more and looks almost perfect today.
Pics show the glass needs to move to the right as well as down

Did you use sealant? If so RedFish most likely nailed it.

It just looks that way.

I haven't put any sealant at all yet. I took the locking strip back out and so I will try and shift it some more. thanks

Get the interior finished (headliner) and we'll go from there. I just installed mine in a 67 cuda and I have "waves" in the same area and my headliner is installed. At first I was pissed but over time they have settled. I haven't tried using a heat gun yet but will eventually. Let your car sit out in the sun and get real hot if that is possible. You will be amazed what that alone will do. good luck
