Problem with Demon rear window gasket fit.

[a34]

Guys,

I'm installing a rear window gasket in a 71 Demon. Precision Replacement parts brand gasket. The glass is flush and the trim fits fine, but inside the car, the gasket is wavy. I don't know what's causing that. Any ideas/suggestions?

Thanks!

Looks like it didn't seat well on window frame. Maybe take a short wood block and hammer and tap it up and seat it.

Maybe a little heat, or just some time to settle, or both.

Thanks, I found a guy on another board who had the same problem. Maybe the gasket isn't quite right.
