i seemed to have lost a couple of wingnuts. instead of driving around with one wingnut on my cutout or pulling one off at the auto store, just wondering if anybody knew off hand what the size of the nut was? i'm gonna throw some lock washers on there too this time.

 

Just guesing 3/8 corse thread.

 

works for me. thats what i was thinking too. ill find out the hard way i guess. thanks for your help.
