What's Needed to Go From PwrSteer -to- Manual Steer?

As we all know, nothing just 'swaps =n= bolts' right in w/ our beloved Mopars.
So, what is needed to go from Power Steering to Manual?

My car is a 1968 Barracuda Convertible: 318/4spd. FWIW, I just converted the car over to post-1973 Disc brakes & Upgraded the Front End (Bigger BJoint UCAs, New Lwr BJoints, C-Body Tie Rods, etc). This thing has a real nice & tight Front Suspension, but coupled with the 7+ inches (!!!) of play from my Pwr Steering Box (not connected), it's a recipe for disaster.

OR

Is it simple enough to rebuild the Steering Box (Pwr) & stay w/ Pwr Steering?

I'm sure this question has been posed before, if so, I'm happy to be directed to the link.
Thanks in advance.
