Yes Art does water pumps as well as fuel pumps.
If you are brave Long Island Corvette Supply sells the rebuild kits for the do-it your selfers (Big Block and Small Block). They are very easy to rebuild. The only thing you need to be carful with is on original pumps with the cast iron impeller it must be supported correctly or it will break. I found out the hard way
good thing I had a pile of original ones at the time.
