I learned (after 20 min. searching through inventory at autozone) tonight that the 7.3 powerstroke thermostat Oring fits the toyota input shaft Oring AND the sector shaft Oring really well. and they are a hair thicker but not TOO thick. score.
i would be weary of using that......would suck to put it together and have it leak still....not sure what the tolerances are on that part...remember the hydro assist might be putting more pressure on those than stock
