Billy. Welcome! I JUST dropped my 89 1-ton long bed off to get the motor centered and mounts made!!
Mine is a '95 Grand Cherokee 5.2 Magnum motor with a NV3500 trans.

It's funny how we (the fabricator and I) were just talking about what people do to "make" things work.. (well, kinda)
You'll have to swap all the parts back to the correct sides, and depending on oil pan clearances, swap in a 'rack' and get
rid of stock steering box.
I'm going to try this route, and use a 3:1 rack from an older Honda civic that I've got, or go 'yardin' and look for a rear-steer rack.

I'd LOVE to see your drivers side engine to steering and booster clearance pics.. I've gotten rid of my booster and will be using (or trying) a GM, Corvette style, dual port master along with a 7" dual diaphragm booster. (not mounted yet)
The stock magnum manifold looks like it would be pointing right at the box.

I'll pm you.
