I wanted to say Thanks!, to all those kind souls who replied with good advice.
I'm going to invest in a 1700 ft lb, 3/4 impact air gun and A 15' 3/8" hose.
It is rated at 1500 ft lbs torque but has a bolt break rating of 1700 ft lbs.
I know a breaker bar and 4 ft cheater would work, I don't have the room to use it.
Besides, who knows when I might need the power for another stubborn nut.
Thanks again!
Wayne
