To all, Does anyone have a source of parts for a TC speedometer? I am looking for the small brass spacers with the tooth on the inside opening, found between the counter wheels on the odometer or trip odometer. I am needing 6 of these. I can fabricate these from proper shim stock, but would like to purchase the "real deal" and thus save myself some workbench time. Thanks in advance for any source leads... Ben, TC 4260
