New in box, Chevrolet 6 cylinder water pump - marked for a 1971 Impala but I'm assuming it fits the range of GM 6 cylinder engines from 1962 - 75.  Box is marked W. Co, Chicago, IL and has part #8630 and 37-1677.  Shows surface corrosion from extended storage, propeller still spins freely and bearing shows grease on edges.  Please see pictures and condition descriptions for better idea on overall item condition and thank you for looking!
