Snailmog,
You'll want to remove your windshield wiper arms when you install the Brooklands-style windscreens. This will leave the raw-looking wiper splined stubs protruding. The splines are 1/2 inch in diameter. You can find 1/2" (or the appropriate metric size) rubber table leg ends in the Morgan department at your favorite do-it-yourself store that will neatly cover the splined end, thus protecting them and looking a lot better, too.
