Just some more screws for the '37 Ford .... After seeing your website, I can not get over the variety of screws, bolts etc; with such a vast variety of thread sizes, pitch etc ...... Try getting 12 - 24tpi screws from Bunnings ! Doing up the old PickUp and also working on Norton, BSA & Early Harleys, these vehicles have some damn strange threads ... BSF, CEI, BSW, etc; etc; [bloody poms ... ha ha ha] but it is great that we can obtain all this obscure hardware from you guys.
