Also, as far as I can tell, nobody makes an install kit to just change the gear set. Even the dealers are swapping out the center section vice changing the gears. I ended up swapping my Mettingen one legger with 3.06 for a Getrag posi with 3.73's.
I calculated it up, and if somebody did make an install kit for the Mettingen, by the time you added up the cost of the gear set, install kit, and a posi unit (Wavetrac or Quaife ATB Helical) and everything else, the cost difference between building up the the 215 and swapping out to a Getrag was less than $550. Neither option is exactly cheap, but swapping the entire rear and axles not only gets you the gear set you want, but the Getrag is much stronger.
