While sifting thru an "experienced parts emporium" yesterday, i came across a pair of extruded aluminum rather than plastic windows. Measurements worked out to being the same as original plastic made by Go Industries. These appeared to be new, but had tempered glass which means no flex to meet curvature of main cabin. Does anybody know who manufactured these windows? Like to get a set made up with acrylic or hardcoat lexan. Hoping somebody out there has run across these and can help. Carl Foster
