Need help with windshield and rear window install on 67 barracuda

There is a space between the where you would like for the gasket to be and where it actually sits on these cars. Its covered by stainless on the later but it's still there. The 67 gasket has a little larger profile and fills it better but not completely. Then the gaskets shrink with age.
If you have to stretch the gasket to get it on the glass, it shrunk.
