I replaced the cap for the Master brake cyl. on my 61" Econo with one made for the 55" - 57" Thunderbird from NPD in Canton. So for anyone lokking to replace that cap and gasket that lives in Michigan shop locally, because our Economy SUCKS here right now why send your money to NYC or elsewhere. And for anyone else it could be that much easier to find at your local swap meets or ordered at the local auto parts store.
