The problem is that the nut had to be severely molested using a plumber's wrench after failing to yield to Heat, PBB, Freeze-Off and prayer. But the unit itself is fine. At this point the plan is to grind it back to a two sided shape that will work with a wrench and risk the concourse judge's ire. If that left eyebrow goes up more than a quarter of an inch, I hear I'd lose 32 points. I'd be devastated.
