I am putting an XK140 back together. It is an late model with C head. I am installing a new wire conduit. Did Jaguar put a D washer with the two mounting tabs of the conduit or a round beveled washer or something else? Also did the washer,if used, go on top of the tab or underneath? Finally the parts catalogue says 4 round washers were used and 10 D washers. I know 2 round ones go on the two studs on the front of the engine. Do the other two perhaps go on the tabs or perhaps at the rear two studs? Perhaps there is a picture in the manual but haven’t seen it.
