On my 65 just one hole above the rectangle hole (for tranny neutral switch), but a dimple on either side like the hole could be punched for something, On my 66 I have two holes punched, the large one above the left side of the rectangle (for tranny neutral switch), and then another to the left of that hole (power top wire), Maybe the one on the right for a car with air conditioning? I think the hole above the the blower motor shouldn't be there.
