Im adding power steering to my slant six and the dampner on the donor six had these 3 locater nubs for the pulley, plus 3 bolt holes.. It was an auto. My dampner just has the 3 bolt holes and its a stick plus has a crank bolt. Do I need the donor dampner or can I bolt the pulley to my dampner with just the 3 bolts? Donor dampner was in rough shape plus It appeared to never have a crank bolt. Heres a pic of the donor six dampner after I removed the pulley.
