Proportioning Valve - which one?

OK AJ - I'm learning some good stuff here! This is what is nestled under my master cylinder, it accompaned the manual 10" drums all the way around. I had bought a complete set for converting to KH brakes - including the pro valve, but then decided that I wanted the wheel choices offered by the 4.5" pattern and went with the single caliper setup.

What is it that you are suggesting I do with this piece that came with the car? If you are saying that I may not need anything there, do you gut the insides out, keep the block place? I don't mind the work of plumbing, bleeding or any of that, I just want to do it correctly, have a fun and safe car to drive.

There won't be much of a stagger in the tire size.

Members like you all are why I come here for help and support the site. I totally appreciate your time.
