The plate came sometime after the switch from the four bolt pumps in 1963. Not sure if the plate came with the change or later.

694.1 - that pump looks a lot like the pictures I have seen of the cast impeller pump sold by NAPA. Maybe it is the same as I don't know about NAPAs supplier. Keep posted about the performance. I can't tell if the OD of the impeller is as large as the impeller I have or not. I can see a difference between my old stamped impeller and the cast one which I think has an effect of the performance. And maybe the lack of holes from the back side will affect it also.
