does anyone know if a front center window from 75 argosy would fit our 69 tradewind? I know the hinge would have to be switched. Guy has one for sale, is single pane, and appears to be the same measurements, except not sure on the hinge. From the picture I can't quite tell if the hinge on those is part of the frame or rivited on. Was hoping someone on here could help. Is the argosy hinge part of the frame or riveted to it? Our front center is plexiglass and we'd like to replace it.
