Help with steering shaft coupler and new power steering box

[CJocho]

All,

My base model 84 Scrambler originally had a manual steering box. Several years ago, when I started this project, I bought a power steering gear box as a replacement. I do not have the paperwork for that purchase so I'm not 100% sure of the model gearbox I have. My best guess is that what I bought was a Cardone 27-7595. The new power steering gear box has 31 splines on the input shaft with a flat and notch and is .80 inches in diameter (see attached picture). My question is this, how do I get the new power steering gear box to fit on my stock steering shaft? From the measurements I've taken of the stock steering shaft, the coupler of the stock shaft is too small (about .70 inches in diameter). Here are my questions:

1. Does a company make a coupler that I could use to replace the stock coupler on my steering shaft?
2. Is the coupler on a stock steering shaft for a manual and power steering different sizes?
3. Would it just be easier to acquire an original power steering gear box?

Your stock shaft is for a manual box. It will not work with the power assist box. You will need to go to a power steering shaft to make it work. I would verify what box you have before finding a new steering shaft.

Alot of aftermarket shafts are MUCH better quality/design than factory shafts.

There are 2 shafts mentioned above... specific for manual vs. power steering.
Aftermarket ones are good as well... but make sure you specific "power" steering.
