nothing lines up...wtf

Looks like the pulleys are for a short waterpump, do you have the stock Corvette pump on? It has it's own lenght dimension slightly longer than a short pump. As for the power steering I don't know, I looked into this set up awhile back and was told there is no direct cogs bolt up for c3's.

Are you sure it's a short water pump? If so, then they sent you the wrong pulley.
I believe the difference between the vette short water pump and others short styles is the vette water pump used a thicker shaft.

Dimension from block surface to hub: short pump = 5-5/8"
Dimension from block surface to hub: long pump = 6-15/16"
Dimension from block surface to hub: Corvette 71-82 = 5 16/16

His crank pulley has a V belt grove forward of the cog pulley, I think it needs the V grove on the aft side to align with the power steering. The stock power steering and pulley mounts real close to the frame with little room to move forward. Can it bolt on reverse? Sounds kinda Bubba but maybe the alternators mount could be switched to align as well.

water pump is correct.... short vette.... i had to send back the wp pulley to have remilled at .75...
in his diagrams it shows the vgroove pulley outside the crank.... i thought the ps belt was inside and not outside....i might be able to mount the alt bracket different.....i couldnt find a decent alt bracket to mount on pass side either... so i have to double up on the driver side with the the alt and ps.....
i stopped after i realized this so i wouldnt throw anything since my dammit tool wasnt around........ i closed the hood and went in the house.....

Hey B, don't worry you will get it sorted out. Sometimes walking away and going back to it in a calmer moment is the best choice. It looks like to me that either the water pump is the long version, or the pump pulley is wrong. I have the March serpentine set up, and the pump pulley rides very tight to the pump body-like a few sheets of paper tight at the closest spot at the top! These aren't the greatest pics, but maybe they will help you somehow:

Look how close my pulley is to the pump in this pic:
See what I mean? I think the pulley is wrong!

Taken from the Edlebrock site:
short pump 1: 1969-70 350 c.i.d. Corvettes and 1955-72 light duty trucks. Has 3/4" ball/ball bearing. Dimension from block surface to hub: 5-5/8
short pump 2: Fits all 1971-82 S/B Corvettes. Comes with heavy-duty 3/4" ball/roller bearing. Dimension from block surface to hub: 5-13/16"
long pump: Fits all 1969-87 S/B Chevy or 90° V6 passenger cars and 1973-86 light duty trucks. Does not fit Corvettes. Dimension from block surface to hub: 6-15/16"

I was trying to compare the stock Corvette water pump to the short water pump, the visial difference between the standard long to the standard short pump is obvious with a wider gap between the back of the pump to the timing chain cover, what confused me is that both standard short and stock Corvette pumps (both with different lengths) almost touch the timing cover identically.
