steering issues

[scott123]

1969 1/2 ton SWB 4WD.

Swapped out the 292/3spd/T-221 Rockwell for a 350/350/NP-205.

Drove the truck without issue for a year or so and then did a cab swap and went to a 383.

Truck sat for a couple years after that and a few months back I got back on the project.

The steering which was pretty good/decent before went to crap. One to one and half turns before the wheel moved. The steering box was spinning with the steering shaft but no response. I thought maybe by sitting a seal or something had went bad so I replaced the box with a Cardone re-man. The issues were the exact same. No difference.

I figured the odds of getting a poorly prepped re-man were pretty good so I shipped it back and go another and ended up with the exact same thing.

Nothing is slipping, the shaft turns with the wheel, the end of the steering box turns with the shaft.

The pulley to the power steering pulley is 1:1. Can there be an issue with the fluid to and from the box? No whining/leaking or noise.

Just no movement.

Sorry for the length.
