Picked up a Offy Y-block manifold for free today. In great shape no stripped holes. Only thing I see wrong is one stud sticking out on the back side of the manifold has been cut off. Anyone know what they are for? You can see one sticking out in the middle to the right in the 2nd pic. The one next to it is cut off.
The two bosses on the back of the manifold are for the original linkage bellcrank, as used on 2 barrel equipped sedans, pre '57.
