Ptiman/Steering Arm?

[Tims72blazer]

I've read a few of the posts on changing steering or pitman arms to correct for a lift. I have a 4 inch lift on my 72 K5. The person who owned my blazer before put the lift on it and not the steering corrections. My power steering box started to slip a few weeks back so I replaced it. I figured it went bad from the added stress of the steering angle. Now I would like to put in the corrected steering/ pitman arm. I am having trouble finding one without buying the whole lift kit. I was wondering if anybody knows were I can get one? Thanks in advance for your help.
