Power Steering box identification

Hi every one,

New guy here! Just bought a 76 CJ5 with a couple mods on it!
I'm from Quebec, Canada
First Jeep for me... a friend of me bought a 75 Toyota Fj-40 and convince me to go Off-road



Mods I'm aware:
-full fiberglass body
-33''
-Chevy 327 V8 (from a 68 corvette)
-Front disc brakes
-Power brake (was it stock?)
-Power steering


I have a few questions regarding my steering box if anyone can help
Here's a few pictures of my steering box:




I know it's a Saginaw with inverted flare connections...but I'm not convinced that this is a CJ box...

Both lines are 3/8'' OD
Pressure line was connected to the front port(3/4) and return line was on 5/8'' port.

I ordered a rebuild kit and new steering shaft coupling and coupling does not fit, it's too big.

Last thing.. the top nut (requiring a spanner wrench) is a pita to remove... any idea were I can find a tool or something to help?

Thanks a lot

Looks like an earlier Jeep J20 box with a 3/4" Steering Gear Box Input Shaft Diameter.

Power steering gear boxes for a CJ would have a 13/16" Input Shaft Diameter and no protruding nipple.

Keith may be right. Can you measure the front round part of the box? That will help a little. The J20 box is bigger, and is a popular upgrade to a CJ.

I believe the J20 box is 4" on the end, whereas the CJ box is 3.75".

Definitely not a CJ box with that "nipple" protruding from the end of the input shaft. J-truck boxes do have that protrusion as they use a rag joint vs a bell coupler that CJ's use.

Outside Diameter is 3.75'' Piston looks like 3'', could be a old J10 box?

Could be a Waggie/J10/Cherokee. Those have the smaller, 3/4" input shaft.

I don't know the answer - haven't pulled my (non-stock) Saginaw box ever so don't know much about it. But these guys know everything so you probably already have your answer. As for power brakes, they were an option. I don't have 'em on mine. Someone drove mine the other day, just around a parking lot. Climbed out and said "there's something wrong with your brakes! I could barely stop!" hee hee. If you have me walk 100' I'll probably veer to the left a bit due to the stronger muscles in my right leg...

Meanwhile, great find! Looks just the first CJ5 I ever rode in back in the late 80's.
