On my 72 D100 project the Power Steering gear box is leaking pretty good & I was planing to just get a reman from NAPA. I was curious though if there are better options that would be a quicker ratio.
Anyone recently upgrade thier steering gear box?

Anyone recently upgrade thier steering gear box? I'm looking for same for my '79 Power Wagon. Looks like I'm going to end up with NAPA too.

Gene is correct about the 1972 having some one year only parts. I think the sway bar was a one year only deal in 72. (It was a better design.) I can't recall any differences on the steering box, but can't guarantee it's the same as the later trucks.
I know on the later trucks Dodge offered 2 different ratios. The majority of the trucks were about 4 turns lock to lock. There were some that were a bit faster with about 3 1/2 turns. Neither of these are even close to being a fast ratio box!! If you are looking for road feel, you will probably be a disappointed also.
There was a company many years ago that created some fast ratio boxes by swapping some internal parts. The odds of finding one of those fast ratio boxes is not very high. They have probably been out of business for over 10 years. I only mention this because there is a way to convert these boxes to a faster ratio. Unfortunately, I do not how they did this conversion.
I'm also going to be looking into this subject. Once the temperatures warm up so it it tolerable to work on the truck again!

I have no personal knowledge, but I have seen it in several places that, basically, corresponding year GM pickup boxes will fit, I think a bolt on.
These have a faster ratio, or variable ratio.
I have looked at some, but never had them both off the trucks at the same time, but they sure LOOK interchangeable.
And I think the Dodge box is a Saginaw, too.
Thing is, I am looking at my 85, and don't know about the 72 box.
There was something weird about the 4wd boxes, I can remember installing P/S on an early one (72 3 or naybe74)and after finishing up, starting it, and the wheels went in opposite direction of what the steering wheel was turned.
I can't remember exactly what the screw up was, 2wd box or before/after date of steering changeover, or what, but for some reason I DO remember it was a red short bed Adventurer w150.
It takes gasoline to interest me.
