I have been considering two different options. The first option was to try and rebuild the AGR box, because as it sits right now, I have 1 finger steering without the crossover set up, and running on 37" tires. And then convert it to a crossover set up, with the option of adding hydraulic assist afterwards. I got a rough quote from AGR for what it would cost me for them to do the work, and for changing the shaft and drilling/tapping for hydraulic assist would cost me about $225, without shipping.
The second option was basically what you said, but with going with a Redneck Ram setup, because it would be less expensive.
