I also purchased a factory 1.25" sway bar from a board member. This truck didn't come with a sway bar, so it should definitely make a difference.
After we got moved to SC, progress slowed quite a bit. My dad fell off a ladder at home and hurt his shoulder. He ended up having rotator cuff surgery. Not too long after that, he also had hernia surgery. On top of that, he was responsible for taking care of my Great Aunt who was in declining health. Therefore, there was not much time to work on the truck. Not being there to help, all I could really do is gather parts that would be needed.
I ended up buying a new Fenco power steering gear box & Lares coupler/rag joint for a '72 C-10. I used online discount codes from Advance Auto Parts to get it cheaper. Then I bought a "Captainfab" power steering adapter plate, along with the steering shaft adapter/coupler he makes as well:
