Datsun Roadster & Fairlady 63 - Mid 66 Early ROUND Valve Vent Rubber (Pair)
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.
DIAMETER 4 1/4"
