68 C10 Converting to power steering

[ron lechman]

I have a 68 C10 V8 that I would like to convert to power steering.
My truck currently has the original manual steering it came with. It was a 250 six cylinder standard shift truck now a 305 AT.
i have a good power steering pump that I`ve already mounted.
I have a good power steering box from a 73 - 78 C10 that I have not mounted yet.
My questions are:
Can I reuse my original manual steering parts such as the pitman arm, the idler arm and the center link.
If not what if any parts can I reuse.

I`m tired of the armstrong steering during parking.
Cheers!! Ron
