I've been looking into running a KRC pump (GM type II) for my 440 and I was just about to ask if you've looked into the Unisteer bracket... until I read further down the thread, lol!
I started off buying the bracket kit from Unisteer but after I bolted it on I decided it was too crappy of a design to use on my car.
That was the only bracket I could find that was on the market.
I'm interested as well if you have a set laying around. I'll be in Oregon next week.
My plan is to swap over to a 1 wire alt, low mount Sanden A/C compressor, 440 Source 6 rib pulleys. I plan on running hydroboost as well.
