power steering belt

[66_k10_manny]

I have a 66 K10. I did a power steering and front power brake conversion a few years ago on it.

I installed a power steering pump bracket from Summit Racing and I think the pump is from a '77 Camaro.

Problem is: No matter how much I tighten the P/S belt, it slips and squeaks; especially in the cold temperatures. The last time I tightened the belt, I used a pry bar to get enough tension on it just to stop the squeeling at warm temperatures. I can imagine I'm putting excessive tension on the belt not to mention on the pump but that was the only way I could stop it. I was advised to try another P/S bracket but will that really help? Won't that just change the location of the belt?

Advice?!
