Brad,
What would be the part number at Chevs of the 40s?
Adam,
Are you referring to the
oil connector (1954) in the middle of the two rocker-arm bars,
which changed over the years (1959)? You will need the style of connector that matches the year of of your rocker-arm assembly, that hopefully matches the year of your head (that hopefully matches the oil-supply plumbing on the year of your block). If everything is from 1962, you will most likely want a connector as shown from in the 1959 manual (I'll check later manuals tonight).
When
Pre '68 Dave sees this, he'll correct and clarify what would be needed in 1962.
