Ok. Thanks for the feedback all. Got some new pins coming, going to replace all the rears as a precaution. Interesting note on pins too long/wheel to shallow. Will double check this go around, for flush wheel to hub fitment.

I'm really at a loss as to what happened.
I do recall that I drove the car home from the garage last time with no safety wire. Once home I wired them. Though the spinners were tight, I suppose its possible that one wasn't and broke and tightened itself down further. In any case the safety wire didn't budge in the couple hundred miles I put on after that.

Though even if it broke later, I guess the wheel rotation could drag the nut forward via the safety wire without breaking it. Spinner was tight into the wheel, which was tight into the hub, it was tough to get it all off.
