Smile 72 C20 a arms to 70 cross member

Are there any issues on swapping the a arms from a 71-72 C20 to a 70 C20?

I want to install disc brakes on a 70 C20 and I have all of the parts. The cross member that I have on the truck is good and I believe that my only issue is moving the support brackets for the brake line.

Looking in my Moog catalog, should be no problem, The control arm shaft kits are the same for those years.
Install your new spindles/rotors, see where your brake hose brackets need to be.
