Also quite true. While I didn't need to do it, the welded or rivited disc 
could then be trued up by chucking the entire pump in a lathe (8" or larger) by 
the shaft and turning the disc's OD. I might mention that the WEiand on mour 
car has been severely modified: I added the disc, weld-repaired the cracked boss 
and chopped some 3 lbs of uniused boss, etc off the outside of the poor 
thing. Its cooled adequately for our 10 minute long run at 145-150 mph a few years 
ago, and has caused zero trouble for nearly 20 years. 
Plus, there's a few shops in major cities that will overhaul most water 
pumps, changing seals and bearings if you send them the old pump. I haven't needed 
their service but if I was Bob Benson with a collection of pumps, I'd gather 
up mt expensive scrap and see what they could do. Cheers- J DeRyke
