Need help

[lts70]

I have been having problems keeping my power steering belt on my 70 chevy lately, the power steering pump sticks out a smidgen more (1/16" at most) than it should for some reason. I shimmed the outer crank shaft pulley with washers to get it lined up a little better and that worked accept at high rpms occasionally. I just installed a three pulley crank shaft and water pump system and do not want to shim it out as it will cause the other grove to be off by a bit. So my question is can I run my power steering using both my crankshaft and water pump pulleys? I have never seen it done but don't know why it would hurt. I am hoping buy running it on a longer belt and with three pulleys instead of two it will be less likely to keep flying off. Thanks in advance for any help, I am getting tired of driving it as my daily driver with a 15" steering wheel and no power steering, maybe I will have to go back to the captains wheel it came with if I cant figure this one out.

Here is a link to a previous thread with pictures and more explanation of my on going problem.
