I wish you would have shared your trick on how to get these things in. I’ve been fighting the sail panels on my 75 Duster for about two hours now and cannot get them to go in. I did a search of images on the web and I see the sale panels over the top of the rear window rubber gasket and underneath. Underneath looks like that is the way the factory did it and I can get them to fit over the top, but it just doesn’t look right. Any suggestions on getting these d*#n sail panels installed without cracking them?
