Steering Box for SAS?

[RotorFX4]

What is the best or easiest steering box to use in a SAS in my 2002 FX4? The Axle would be a narrowed HP D44 out of an 78 F150. I will be using a 3 link setup. I am thinking about purchasing the F150 steering box as well, but If a steering box out of an earlier Ranger or BII would work better, I'd rather use that. Any advice is greatly appreciated.

thank you
