I think I have 200 plus hours fitting the rear window, on the BJ 7/ Bj8 top, I think the top is more rigid and using the window stays would not really help. Not that it really maters, its your car but the BJ 7 and BJ8 did not have window stays. It's about getting the window lined up so u can drill the screw holes, I think Pete F tops are shipped assembled.
