I have a model 3 that I keep in a trailer as my hanger. I fold and unfold the wings every time I go out to fly. I have been noticing that the pins that attach the front spar to the carry-thru are not as tight as they used to be. Nothing terrible, but I am keeping an eye on them.

Does anyone know if there is a spec for the clearance, and if it the holes wear too much, how do you fix them?

I have been thinking about making a steel collar that would go on the outside of the spar with new holes that would tighten up the clearances
