Putting AC on a 289 with a KRC p/s pump

Has anyone had experience with adding a Sanden 508 compressor to a '65 with a KRC power steering pump? I'm thinking about using this bracket set, which looks like it would fit behind the KRC pump bracket, but I'm not sure about belt routing. I'd like to not learn that something doesn't work after spending a bunch of money.

Thinking that I need a bracket set with an idler pulley on the alternator side, like this kit (see instructions for pictures). Should sit well above the power steering pump, so no clearance issues there.

something for you to think about, I installed a vintage air system in my 70 with a 351 Cleveland, at first I ran one belt around everything but the alternator, it worked but I really didn't like it, so I reconfigured the mounting bracket so it hinged the opposite way, ran the belt in the original configuration, then put a double pully on the power steering pump and ran a short belt from the power steering pump to the compressor..

I used a kit from Classic Auto Air that came with all the pieces and brackets for the set up the car had in it.

If you run an idler then you really need to use a "toothed" V belt.

You can't go wrong with a March kit. For $840 you'll have a beautiful set up with all new pulleys, everything matching perfectly and a single serpentine belt. It puts a large "wrap" on the alternator, so even if you upgrade to a 140 amp it will never squeal. It mounts the AC compressor low, on the passenger side, and out of the way so you don't have big ugly hoses running over your pretty engine.

It's one of my favorite parts of my build.

A little black paint and those will look good.

I'm generally pretty short on cash, so spending $840 on a serpentine kit is kind of out of the question. Besides, I've already dumped a bunch into the March V-belt pulleys I currently have, and I'd like to keep the KRC pump if at all possible. I am intrigued by the idea of using a multi-groove pulley to act as a sort of PTO for the AC compressor. Perhaps I could reconfigure the power steering belt to skip the water pump, and then run the AC off of the extra water pump pulley?
Edit: looks like the PS belt would just hit the WP pulley. However, there is a 3-belt water pump pulley for use with smog pump equipped cars. https://www.summitracing.com/parts/t...view/make/ford

The set comes in black for an additional $0. That's how I dressed my FE.
