So two (#2&4) of the largest bolts fit the 2-3/16ths socket (tight) and two (#3&6) don't. I remeasured and sure enough the ones I can reach are 56mm and 57mm. Looks like I'll be buying an additional socket... 2-1/4! I should have heeded Ken's advice more closely.
What are the chances they used different size studs/nuts verses the chances that the tolerances on the nuts simply allows a 2-3/16 socket to fit a 2-1/4 nut?
