You really are trying to overthink this. Input size is irrellavent, the flare versus o-ring pretty much the same. Turns lock to lock is the main difference and it is what determines the ratio. Remember the cj5 is a short wheelbase vehicle that sits high and is prone to body roll. If you put a fast ratio or low lock to lock box on it the jeep will be twitchy and will steer very fast on the road with little input, think sneezing and changing lanes in the split second your eyes close. I would not put a variable box of any kind on a cj5 myself for much the same reason. 13:1 ratio would be the quick 2 3/4 turn box like what is on a Camaro or sporty car that you would run on a track. The 3 1/2 turn would be the 17:1 ratio and the 4 1/4 turn would be the 20:1 ratio that was standard on most power steering equipped cj's. I have the 3 1/2 turn box and would rather have had the 4 1/4 turn box as it would take a little more input and would not make the jeep darty on the road and gives you more road feel.
my p/s box came from a donor 73 Wagoneer.
4.5 lock to lock
nice and slow
I used a rebuilt CJ box from Lares corp, avail through Advance Auto.
Click on catalog, scroll down to Steering Gear, Jeep, CJ.
Box # 1100 was right for my application, flared fittings.
They also make a "Rock Crawler" version, same size and ratio, but more robust components.
friend of mine used one from a pontiac trans am. i used one from a 84 camero. both are quick ratio. got them because the price was right. they both worked perfect and no problems. id say whatever one you can get the cheapest.
Mine came off a mid 70s Waggy.
I'm using CJ p/s pitman arm on the waggy box
lock to lock, no worries, no wheel spacers.
works fine for me
