Right, my '67 Fury is a 4-door hardtop and has the rear vent, so there's that grille in the dutchman panel. Because the car lives outside, and trees are a thing, there's some debris in there--mostly small leaves and those helicopter things maple trees shed.
Have any of the other 4dr HT owners here figured out a way to clear that out? As far as I can tell, there's no way to access the area under that grille.
