'67 C10 Power steering Gear

[bensimmons_05]

This question has most likely been presented a number of times but I searched for a while and could not find a clear answer so if someone could provide a link to the thread with this info. or just tell me it would be much appreciated!!!!

What steering gear from what year pickup (2wd or 4wd) and/or adapter kit (and from where) do I need to convert a '67 to power steering. I can make a pump work but for now I just need info on the gear.

Thanks guys!!
