Windshields?

My understanding of the 67-76 windshields are that the 2 and 4 door sedans share a windshield, 2 door hardtop (swinger/scamp body) use another, and Duster/Dart Sport/Demon have a third windshield. So 3 different windshields for 67-76 A bodies (and I have no idea how Barracuda falls into this landscape)!
