Quick ratio steering box ???

[gregbr]

Any one know of a 3 1/2 turns approx lock to lock, power steering gear box for a 4wd that uses the old style flare fittings? I have heard here that there are 2 models offered in 73-77 4wd trucks, 1 is a 3 1/2 trun & the other is 4 1/2 turn. I have the 4 1/2 turn already (stamped 7802644), would like more info on what truck to pull one from oe even a casting number. I recently picked up one from a 85 4wd (marked 7802644L) that is 3 1/2 turns, but it has different fittings on it than the one I have installed. Doesn't look like I can use the later model pressure hose since my pump mounts down low next to the balancer & the hose routes up the side of the pump, the later pump is mounted up high and the hose routes under the pump to the gear box.

Any ideas?? Thinking about swapping the guts of the 85 box into my 75 or so box to retain the flair fittings.
