Dana 300 transfer case

I am planing to purchase a dana 300 soon to replace my 231 I need to know what I need to make the 300 work. I already have a jeep 300 so it is a 23 spline input shaft and my AW4 has a 23 spline output shaft, I will be making my own shifters, so I think I just need a clocking ring.

its a passenger side drop case, so you're gonna need a passenger drop front axle
