Windshield install advice.

I have to unwrap it.

The 1967 cars have the bed lock, I know I've seen the one dusters have that goes around the top and down the sides..is that what you're referring to?
Naw. On the early cars like my 64, the gasket has a wide slot in the center that the lock strip installs in and locks the windshield in place. There are two distinct pieces. The gasket and the lock strip.
