Gp. 1.003 Pn. 3704162 water pump shaft assembly w/bearing, 4 11/16” O.L., $3.45
55-57 All. It went thru many parts number changes after that but was the same shaft
assembly.
I sold a lot of them and installed them at home when I was a Chevrolet parts man back in
the early 60’s.
As Brian said, you may get lucky and find one on evil bay but the rebuilders have
cornered the market and are the only ones that are able to get the new assemblies now
a days.
Much like the kits for the vacuum wipers, which are dominated by one rebuilder today
who won't sell you kits, only units rebuilt by them.
