Yeah I couldn't see those little pins holding under what it takes to bust that retainer nut loose. Mine was rusted...from the factory and it has some god-awful thread locker on it. Took a 1000ftlb air impact, heat & PB Blaster and several rounds of choice words to get it off. I didn't use the holes, I went into the webbing and built these solid steel blocks custom ground to fit all the way down and follow the taper.
