Well that was an easy fix. It was just a bolt that broke. That side had a 5/8 x 5 1/2” and the other side was a 6” with different markings so I’m not sure if the one that broke wasn’t a grade 8. I’m thinking it was one they had laying around or a Chinese knockoff. I bought grade 8’s and did both sides. I’ll probably look into getting some stronger ones. I’m not a metallurgist so I’m not sure what can be gleaned from the break, if any.
Also while I’m fixing this I notice a socket is missing from my new shallow set. Guess which one is missing?
