HELP PS gearbox

[jeepboy45]

OK JEEPERS.... Looking for some quick intel on a saturday afternoon... LOL

I have been talking about PS gearboxes in diff threads
However I need some quick help.
I have a 79 CJ7 .
Found a 2003 wrangler with 37K on it and he has a gearbox for sale.
I also found a 94 YJ...


Can I use either of these gearboxes?
Will it bolt up?
I understand that the lines might be different ( flare vs. O-ring)
Ratios?
Turning radius?
What about how the steering shaft hooks up to the gearbox.. is it the same as my 79
HELP...

Going there today and get it if I can find confirmation..
thanks in advance.

All Saginaw gear boxes are basically the same. If its a Saginaw box it should bolt up. Not sure about the splines though.

check the diameter of the input shaft, there are 2 diffrent sizes
13/16 and a 3/4
take a 3/4 in wrench that has a 12 point box end
if the box end fits over the shaft it is a 13/16 shaft
if the open end fits over it, its a 3/4 in shaft

It is an easy fix but you need to change the knuckle on the bottom of the steering shaft that attaches to the box

now as for the splines on the box I cant remember if they are the same

hope this helps
