Yeah,  I used the wrong term "crow's foot."  I'm thinking something like 
these I've seen used by aircraft mechanics:


Since the wrench end and the box end are aligned I think you'd get the 
correct torque.

Anyone know offhand what size Big Healey head nuts are (probably 11/16" 
or something goofy like that)?
