Windshield installation
A new windshield makes the whole car look better, especially if you are driving it!
The factory shop manual gives a great step by step procedure on installing one in your 67 - 68 Cougar. Basically you lay a bead of butyl rubber sealant into the inside groove of the gasket, then install the gasket on the windshield. Next you lay a bead of sealant into the outside groove of the gasket. You install a piece of twine into the channel all the way around the gasket and tie it at the bottom center, approximately. Then situate the window so the gasket is in place on the body at the bottom. By gently pulling on the string the gasket edge curls over the body and the windshield is installed. It sounds a lot more complicated than the process really is.
Important tips would include:
1. Istall a complete new set of trim clips before installing the windshield.
2. Don't try to reuse an old gasket.
3. Install masking tape, newspaper etc. to protect the headliner and upholstery from the black gooey sealer.
Black butyl rubber sealant is available at any auto paint store or at Home Depot, Lowes and other hardware stores. The windshield trim clips are available in Dorman hardware drawers at older auto part stores or in the "Help" section at places like Pep Boys and Auto Zone.
I have installed several windshields since getting screwed by the "professional" installer was becoming a regular event. It's really easy, anyone can do a good job of it with a little patience.
