If you are looking at pics of anything other than a 41, the window frame will be different. Someone will correct me if I am wrong, But I think 41 or 42 was the last year of the metal frame around the rear window. It's been along time since I had my 41, but I think the frame was held in by clutch head screws from the inside (??). I am guessing one of the numerous parts suppliers will have the rubber gasket for a 41 window.
