Old Merc Knowledge Needed

[kmoose]

A good friend of mine is in need of installing SeaStar steering on an early 80’s v6 Merc Black Max. The below pics and nameplate will let the Merc gurus know what I’m working with.

First off I need to know what I need part wise to make it work. I am open to do it piece by piece or a specific kit. If someone here has what I need and wants to work a deal, that would be great. If not would really appreciate help figuring out what I need to get this done and free up some shop space for another project.
