Steering box questions?

[muddpile]

It's that time again to start a few little projects on the Tornado, one of which being the steering. Last year I drove it with power rack-and-pinion out of a Ford Aerostar van, but noticed a few problems.
-With no motor in the front, the steering feels LIGHT
-The Ford power steering pump is stupid loud (common)
-The pump and 25ft of hydraulic hose are heavy and unattractive
-The rack leaks quite badly, and will need to be replaced

So, have two options here:
1. Put in a new non-power rack. The problem being that the Aerostar rack has no measurement the same for mounting as any common rack, so if going Mustang II, I'd need to build a new mount.
2. Put on a GM truck manual steering box with idler arm and a cross-steer setup. I have all the parts I need for this on a 76 C10 parts truck I have, but I still need a manual box (and possibly a shim, some have told me).

At the moment I have a flaming river column and borgeson U-joint that adapts from splined to DD shafting, so I can adapt anything and make it work. Any help would be great, thanks!
