From what research I've done, it looks like you can just swap out the sector shaft in your 4x4 box with one from a 2x4 box. I have looked into this because I did the same thing as you. Paid good money for a new Redhead steering gear and then decided to go with crossover. I contacted Redhead and they told me I could send the box back to them and they would charge $59 for the new 2wd sector shaft and $50/hr. labor, likely only 1 hour labor needed. I do have a spare 4wd box that I was going to try the swap on myself and see how it works but haven't had time.
