PS Pulley Help - Custom spacing needed?

I'm putting together my own accessories for a Holley Mid Mount kit and running into an issue. My KRC power steering pump has a different spacing from the end of the shaft to the mounting face. Everything on the pulley should be the same as the Holley/GM except the dimension circled should be moved towards the pump 0.60" ( or within acceptable tolerances).

Shaft diameter is push-on 0.66" GM Type 2.

I looked all over and the only company listing dimensions such as this is March and they only have 1 option with this shaft and no dimensions listed. I emailed their tech support and am awaiting a response.

Here's the Holley pulley dimensions . Part No: 97-152 or GM 19421325

And here's a photo depicting the diff between the 2 pumps. Holley on the Right, KRC on the left.

Finally here's what that Pulley looks like on the KRC pump set in the position aligned with the belt. As you can see the shaft is about 0.6" from being fully seated.
