84 C10 Steering pump and box on 73' 350??

[YatYas]

I have a 66 C10 which has a transplanted 73' 350 placed in it by the PO. The heads do not have accessory holes and I was wondering if I can use the power steering pump and box that I pulled from a 84 C10. I know with CaptinFab's bracket I can mount the box, which I plan on buying. And I have read from many post on this forum that it is best to use the matching pump that goes with the gear box in order to keep it simple (for pressure line and return to match up).

From additional research I have come to believe that an 84 C10 used a long water pump. How do I use this setup on a short water pump motor? Can I use one of the pump brackets that hooks up to the motor mount and change the pulley to a short water pump? Surely someone has done this.

What bracket should I use?

Will this pump work with my motor?

Can the pulley be swapped and fix my issue, and if so, what pulley do I use (part number would be great)?

Thanks for any and all responses.

Don't know why the pictures are sideways!
