If you don't know, you will need to change the master cylinder. You may also need to change the brake booster and add a bias valve.
There may also be a conversion kit available.

You might be better off with a kit instead of swapping in an unknown axle.

You might be able to use the existing master, but you will need the proper proportioning valve. Rear calipers don't use as much fluid as the front ones, so the master may have enough capacity. Call the manufacturer of the kit to find out for sure.

Maybe he wants to break it with new brakes.

I'm doing it with used stock parts, but $cope creep is still having its way with me...

No, I'm "keeping" that ratio, when I change the axle (again). The truck was built that way, and I like it that way, so even though I've swapped in a 3.55 axle before, I've always gone back to the stock RAR.
