power steering conversion.. which pitman arm?

[andrewpclayton]

Hello everyone!
I am doing a power steering upgrade on a 69 GMC C15 that currently has a manual box. has 350 v8

I have the pump, hoses, and gear box from an 82, bracket and mounts for the 69. What I am trying to determine is which pitman arm do I use, one for an 82, or one for the 69?

besides that pitman arm, is there anything else i need to get this done that i havent considered?

thanks in advance!
