Datsun Roadster and Fairlady 63 - Mid 66 round valve vent (pair)

Datsun Roadster & Fairlady 63 - Mid 66 Early ROUND Valve Vent Rubber (Pair) NOT MADE IN THAILAND AFTER MARKET USA

Fits 1963, 1964, 1965, 1966, 

Scarce and hard to find, Nissan referenced them in the bulletin as the "former" Round NOT Oval, valve vent cold air weather-strip. These are NOT modified late style ovals made to work.
Closes off or opens to allow cold air to come into the vehicle. A must on a cold winter night when you need the heater to work properly as no valve rubber or a rotted valve rubber will cause the heater to become totally ineffective. A nice, detailed instruction sheet is provided with this part.
