The quarter windows were always very expensive from Inter,and include a fair bit inside the door.I had a lot of both AB/C/D line quarters both sides and ACCO quarters both sides.I was asking $100 each,which was less than half the IH price.They are not easy to install,and there were complaints about the price.Then a guy turned up and wanted the lot,at my price.I said I was keeping a set for my D line,he said "no I must have the lot".Cash money and off they went.Dunno who,dunno why.By the way ,the door glasses and winder are the same as the "straight door" commercial ACCO,and probably the same as the "step door"69on truck.I might add that Mk3 windshields are not strictly reversible as two different thicknesses of glass are used,in the laminate.Actually ,things are looking on the Inter scene,I have managed to stall the council,and the price of scrap steel is climbing towards $200 a ton.Regards John.
