Replacing power steering with Manuel steering
I am going the opposite way in my factory 69 383-S. I have all the parts for PS now except the box. The steering shaft was the hardest part to find as few 69 383 cars had PS. I would offer up my MS box but not until I locate a good clean PS box.
It is easier to go MS than PS!!!! Certainly in factory BB cars!
The Adapter and Box is really all you need to go MS!
