JP Magazine misinformation
Well looks like the guys at JP magazine may be misleading people a little bit. Just got the latest issue, in which they have an axle write-up. Part of the information they have is max tire size for each axle. Under the Dana 60 it states 39-42 and the dana 70 it states 44s. They do make one qualifying statement that the stock shafts are small and metallurgically inferior to modern stuff.
I have 39.5 on mine right now and that makes me a little nervous. Does anyone want to swap some CUCV axles under my ride?:D
