Yes, 67-69, but only on V8 engines. L6's didn't use it.
By the way, that P/N (9420534) isn't the clamp I linked to.
9420534 is the clamp to attach the rubber return hose to the metal tubes that are screwed into the steering gear and the pump. The clamp I linked above has no part number because it was part of the steering gear assembly.
