Spring upgrade?

Hey guys, I have a question on springs on a 75 cj. It was my understanding from other boards theat my springs were 2" front and 2.5 rear. Well as you all probably know this is incorrect, they are 1.75". My tub is off to be blasted , welded and painted and I had planned to do power steering and leaf spring upgrade. I guess my questions is this can I still use the rear cj7 hangers or what. I planned to go to yj springs since I have acess to some. Or is there something else I should look into. Thanks Eric
