What are the differences in windshields for 1968-72 A-bodies? Apparently the 1968-69 are different than 1970-72? The El Camino is different that the 2 door hardtop? The convertible is also different than the hardtop?

 

68-69 windshields are dimensionally identical with 70-72 for the same body style - the difference is that the 70-72 windshields have the radio antenna imbedded in them.

There are three different size windshields for the 68-72 cars, 2dr Holiday and Sport Coupes, Convertibles, and 4dr/wagons. The ElCo is based on the Chevelle wagon, so it uses the wagon/4dr windshield. Of course there are clear and tinted versions of each, so there are six different 68-69 windshields and six different 70-72 windshields.

 

Thanks Joe.

I took the windshield out since I found the typical rust in the cowl. What is the difference between 1968-69 upper cowl panel and 1970-72? Is it the antennae feed hole?
