You could just re-drill your existing flanges for the new pattern, and I think Cruiser Outfitters sells new flanges with several different hole patterns, but they are not cheap items. If that's the only mistake you ever make on your Land Cruiser, you are way ahead of the rest of us.Can you buy the flanges to fit the newer shafts to the older trucks? I just spent $125 getting it cut down to fit after the conversion and tehn it wouldnt bolt up. I didnt even think about checking beofre hand. IDIOT!
