I've replaced the windshield and headliner on a 70 B-Body but not an A-Body. First, does the windshield have to come out to do the headliner? IIRC the material wraps around the lip on a B-Body and then the gasket goes over it. Secondly, is the A-Body windshield gasket a "zipper" type like the B-Body?
Anything that much different from an A to a B that I should be aware of, thanks.
