Also.. the internal stop in the steering box are close enough to the A-body one..
That being it would have about the same degree of the pitman arm/shaft turning.. many of the other model (3rd gen f-body, etc) don't turn enough and you end up with not having same full turning radius of the car.
70-72 A-body need 40 - 43 degree, other one that are close are 84-86 MCSS, 92-96Police Caprice and SS's
You can find some info on the Pozziracing and on the Chevelles.com site.
Also.. what comes into play are the lenght of the Steering arms and center link.

Plus, in general, 80 and 81 Z28 and Trans Ams have quick ratio steering boxes with metric connections. Mine is 2 and 1/2 turns lock to lock (12.7:1), and connected directly to a high pressure hose for a C5 without any weird converters or fittings.
So if you know someone with one of these things moldering away in their back yards, that would be an option too.

Those 80-81 box only have 33*30" Degree of turning and might only be 14:1 in ratio..(per my saved notes). If a variable box, then 16-13:1 ratio. Number of turn would only indicate it might be a Quick Ratio box.. but not the Ratio.. you would need to get a degree wheel on it for sure, or if the two letters Alpha Code are still on the end of the box.. that would tell you where it came from and what ratio..
The 82+ had the 12.7:1
The Jeep GC is 43*45" and is a 12:1 box

Best place to find one I assume is the junk yard or would oreillys seem better?

yeah.. most people look for a low mileage one in the JY's... but a rebuilt one from O'Reilly's or Autozone if you can trust them (do your research, can be a hit or miss) will work..
Lee Manufacturing is a good place to buy new or rebuilt ones. But is the more costly option.

I'm asking out of ignorance here, but have you encountered any suspension/frame/tire well clearance issues at the extreme ends of the turning range? I'm intrigued by the extra 10* of steering range. My A arms aren't factory, so there is plenty of space for more turn now...
Also, are there PS pump pressure issues that have to be addressed with the Jeep box? The older PS boxes (like mine) require lower pressure than what the typical LSx PS pump puts out, and I ended up ordering a low-pressure pump from Turn One. This resulted in better road feel for me- steering was too light with the original pump.

I just finished my swap yesterday. WOW what a difference! The OE box felt like piloting a steam ship, the GC box adds some much needed steering effort and much better return feel. On the first drive down our twisty road I felt like a little kid with a new toy.
