I got a new water pump from RockAuto and only broke two of the 3 bolts off removing the old one. Fortunately, I have plenty of drill bits in preparation for such things.
After getting it removed, I was happy to see the water distribution tube was replaced when the engine was rebuilt 30 years ago. Since the engine didn't have 1000 miles on it after the rebuild, the tube looks like the day it was installed. After reading so many threads and watching 48dodgers video, I'm glad this is one thing I don't have to do.
