Does anyone know the thickness of the hood shelf support blocks for a 1917?
Mike, I made a set for my 1917 shooting brake recently. I suggest you make them to suit your hood shelves. Measure how deep your shelves are and make the blocks so that the shelf is clear of the fender when bolted down. The idea is to have clearance between the shelf and the fender so there is no chance of a metal to metal squeek or paint being rubbed off. I had three sets of shelves to work with, and all were slightly different in depth. The new vendor supplied ones come with a large hole for the grommet around the headlight wires. Some 1917 shelves came with a small hole, just big enough for one wire to the headlights. The "Rip Van Winkle" 17 in the black bible shows no hole at all, the wires just finding their way out under the hood. A friend loaned me a set of originals which had an upside down U shaped cut out on the outer edge to allow the wires to pass out to the lights. All were similar in depth but I made mine to suit with almost 1/8" clearance.
Hope this helps.
