I looked into converting my 74 RC over from 4WD to be able to run it in 2 high....I *thought* that I may get a little better mileage and less wear & tear...after LOTS of reading here and on Dodge Truck forums....I realized that there wasn't any benefit to it for me...

Eventually I'll be putting Dana's under it so when I get to that bridge, I'll have to put a kit in the x-fer case....but I'm not planning on doing that for a while until it becomes a necessity.
