Already have the hysteer for my fj40, which came with fj80 tre's. But I need to shorten the draglink. And the GM pitman arm im using on my saginaw box has a small taper, similar in size to stock fj40. I guess i could use a 1 ton tre, but im still gonna have to tap the Draglink and ream my pitman arm. And the fj80 tre's arent that hard to come by, and theyre cheap. But if a shop is more likely to have the stuff to make a 1ton tre fit, then that works for me:awesomework: Not sure how much thicker the taper is on a 1ton tre compared to fj80. Hope theres enough meat on the pitman after it gets reamed.
