This far too heavy sunroof with seized hinges has done the fairly common thing of snapping out the pice of roof holding the hinge . Now faced with a headlining kit discoloured due to water ingress and a broken out anchor point in roof. Halfway through a full refurbishment on my late model Caseih 956 . Looking for tips on the best material to be used in association with material used in XL cab tops. Looks like fibre glass material of some sort. If the designing team allowed for stainless steel hinges and perhaps a slightly lighter sun roof day one then most of the xl cabs would have survived with a perfect headlining upholstery. TIA
