Rocker Shaft Post With Oil Hole

Number 1,3&4 rocker posts. There are 3 of these on your rocker gear all with oil holes although the cylinder head has only one outlet and the single 12G1927 post has the rocker shaft locking plug hole. Some very early cars had the locking post on the end but all current shafts have the locking plug locating hole on 2nd post in so beware.Pre-Owned.
