I've always wondered if a hybrid 80/hilux-60-62 series axle could be done. What I mean is a sort of modified cut and turn project. Cut the knuckle balls out of the 80 axle and see if the hilux-60-62 series knuckle balls will fit into the axle tube of the 80. This would really reduce the cost of high steering on the 80 axle. 
I picked up a set of 1994 FZJ80 axles in sacramento over the winter and have started the above cut and turn. The rear is all cleaned up and ready for leaf soa. The front I have cleaned up and cut the 80 knuckles out. I also have cut the knuckles out of a spare mini truck axle for the donor knuckles to insert into the 80 housing. This isn't going to be an easy build.
From what I can tell the inner 80 tubes are about 2mm larger in diameter than the mini truck tubes. I talked to another member who did this swap some years ago and he stated that he just slipped the mini truck knuckle balls into the 80 housing and welded them up. I'm thinking I'll need to sleeve the knuckle balls to soak up the slop before welding them in. I really want to make sure they run true with the differential so I'll also need to source a long enough piece of solid stock to slide through the differential splines and out the ends of the tubes to get as close to true as possible. I bought the SST for centering the knuckles a few years ago and I think I'll need to use a system like that for pucks on either side to make sure the knuckle balls are centered and have the proper angle to accommodate SOA.
