The PTO rear output is hard to find. It may be easier to get a transfer case PTO, or if your aren’t planning on having a PTO winch, just drive the pump off the front output. I’ve done it both ways, if you need more info.
Edit- I see in your other post where you have a factory pump and valve. You’ll probably have to use a rear output PTO unless you modify your existing pump. I don’t know what to tell you, but good luck finding a rear output.
