Can't find old water pump thread
Hey guys,
I feel like an idiot, but I can't find an old thread that had a drawing showing the dimensional differences between the standard 60's short water pump (with the 5/8" shaft), the C3 water pump (with the 3/4" shaft), and the long water pump.
Do any of you have it bookmarked, or have any better luck than me finding that drawing or thread?
Thanks for any help you can provide, I'm pulling my hair out!

I came up with this after a search on google.
They measure the following from the front face of the engine block to the front face of the water pump hub/fan mount.
SB short style 5.625
sb long style 6.90
sb corvette style 5.80
bb short 5.75
bb long style 7.28
No pictures and I quit.

The best way for a do-it-yourselfer to purchase a water pump is by application to make sure the pulleys line up the belts correctly....{year, make and model} .Any auto parts store can do that for you.... This short/long 
is immediately solved by the year identification and engine size. Parts stores are not out there to sell the wrong parts at least mine is not....If you cant do it right the first time, how the hell will you have time to do it the second time...

Obviously I know now. However, it is on hand today and I was considering machining some parts to make it work- I have a bridgeport and a lathe at my disposal at home. The objective was to have it done for a cruise night that is to happen tonight.
I knew what size to make the 5/8" - 3/4" bushing. I was consideirng making the spacer to move out the pulley out of the same chunk of aluminum billet. However, while I was working on it last night I discoverd that either my water pump or my aftermarket timing cover (there are no true bolt-ons, apparently), are not perfectly within spec, because the timing cover hits the back of the water pump and doesn't allow complete, uniform "crush" of the water pump gaskets. This has to be the root cause of the water pump gasket failure I had last fall.
I ordered the "right" pump this morning- a GM Performance unit that must be a fairly new offering. $113 from Summit (after beating Scoggin-Dickey's price).
