TOPIC: pipestone windshield

have a 1961 pipestone missing the windshield any help with locating
one or a pattern to mfg one

If you cannot find something locally, like an old boat shop with a bunch of salvaged parts, then probably will have to make your own pattern. Start by measuring and cutting a piece of lightweight cardboard, then shaping the profile of the windshield you would like. Then see about fabricating using the pattern: www.fiberglassics.com/restoration/making-a-new-plexiglass-windshield
