Why should I seek when none exist? Our '67 Safari rear window has the top part of the aluminum bar and frame in place but a PO removed the bar attached to the glass and used sealant and screws to fix a piece of acrylic in its place. Of course the acrylic has cracks and leaks and will not open for ventilation. Does anyone have a junker '66, '67 or '68 from which a front or rear window bar could be salvaged? If I hear no other, sounds like polycarbonate, rivets & sealant is one path forward.
Onward thru the fog.
