well my 86 had its windshield replaced, we took the windshield out of a 88 Aries for only 25 dollars, busted the old one all to pieces because it was urethaned in.
Use a Heat Gun (not a hair dryer) to soften the urethane and remove the windshield. About $30 at Harbor Freight, I use mine all the time for different projects, getting paint to dry in winter, etc..
