just picked up a mod 20 from a 83 waggy, as I unloaded it I noticed that it had two peice axles, the shaft is 1 3/4 with lots of splines then the hub looks as if it is pressed on and then welded around the seem??? now I always read that the mod 20 in the waggys were solid axles like a 44, what's up with this?? looks like it should be strong enough but are they all this way or is there years where solid axles were not used?? and I just grabbed the wrong one???
