Quick Ratio Steering Box

I've searched and found a bit of information, though I'm not totally sure of some details. I'm looking for a bolt in replacement steering box that has the 12.7-1 ratio. From what I have found, a box from a pre '92 F-body with the sport suspension will work. I just want to double check that all the hose fittings are the same and that mount pattern is that same a stock. I plan on ordering one from Rock Auto and I don't want to mess up because living out here makes shipping expensive. I don't want to bother with a used one either because the junk yards here are exactly that, junk.

do you live by a nappa? if i remember correctly, they will custom make lines to your specs, fittings, length, diameter.
