Well, here is what March came up with to fix my problem. Who would have thought I would have to spend more money with them? Here is the e-mail from them.
"Well, I am sure we would have a power steering pulley listed at the link below that would fall within the offset you need. Just looking at the photos, comparing to the 530 you have now, I would guess the 510 or 540 would be pretty close to lining up. Now, after talking to my engineer, he said the problem may be that you have a factory bracket that orginally used a Mopar Federal power steering pump, not the GM saginaw pump that you have now. Even though you can mount the GM pump with the bracket, the Federal pump would have had a different offset than the GM pump, which would explain why the pulley is not aligning. My best recommendation would be to take a look at the chart at the link below to get the correct pulley that will align. I apoligize for your inconvenience and understand your frustrations. We do our best to make everything as bolt on as possible, however sometimes you run into unique applications or instances such as this."
