I've considered it and researched it awhile back. My conclusion was that it was not worth it for a 62. It's mostly done by 4runners. I forget the facts but as always, anything is possible if you want it bad.
I don't think anyone here that I know of has done this modification. Some of the guys that have been under their trucks longer can tell you why I'm sure.
I know on my 82, there isn't a lot of clearance between the tranny and the body. It would take a body lift and then raise the drivetrain accordingly. And the t-case isn't clockable that I know of, so no way to get that out of the way without raising the entire thing. Now maybe there is a clockable doubler or adapter out there?
