I have a 1937 Plymouth that has had the original headlight buckets removed and a salvage ring installed to carry a standard seal beam. I also have an original set of glass lenses that I would like to use again. I would like the seal beam to be adjustable behind the glass lens. I am willing to use the smaller seal beam if it will improve the surrounding space for the adjuster screws. Does any one know how I should go about doing this? I am also in need of a set of rubber gaskets for the glass lenses. Any suggestions on where to shop for such an item?
