Manual Steering Box

Seasons Greetings to all:
need to get either a new steering box for my 84 Ram 50 or have mine rebuilt, anybody know of a place where
they rebuild the gearbox (great if here in Las Vegas), or, if anyone knows where I can get a rebuild kit...don't want to steal it off of my 85 (attempting at stuffing a 95 3.2 SHO motor into it) and would need the box to steer that one.. the 84 is my daily driver, and would really like driving it without having to wrestle with it on the road...any help would be greatly appreciated .
