1971 to 1978 are the same, wagons ,sedans and hatchbacks, 79 and 80 are glued in and have a trim piece in the inside that goes around the side top and the other side, and a filler strip that goes on the top of the screws that hold the dash in at the top, had to use the glue in one on a 73 pinto because at that time you could not find the rubber seal anymore , now someone is making them , also you had a plastic spacer at the bottom to hold it at the right height when you glued in the windshield , I noticed the glass was over an inch taller and wider than the seal type , and I know what you mean on the Studebaker's , had a 59 and later 60 Lark 8 , then got a 61 Lark with a cracked windshield , could fine new windshields for the early lark , but not for the 61 up, that was over 35 years(or two wives) ago,
