Wing nut with a long sleeve, normally used with classic Mini 1000 or Austin America air filter housings. No longer available new, so we try to keep used ones on hand. These can be cut down to a shorter length for other types of installations, such as Mk1-2 twin carb original air filters. This is a USED part; sold each. Actual condition may vary from photo(s).
Please note that the "wings" and sleeve length of these nuts may differ somewhat, depending on available stock (see photos).
