Dash Defrost Holes

[ykf7b0]

I have a 55 Bel Air Sport Coupe with the deluxe heater option, and I have a question I would like to ask please. I am working on the heater box and all parts associated with the heater but I'm just getting started. My question is, how does the windshield defrost with no holes on the top side of the dash and with the dash garnish installed?

I'm going to answer my own question. I suppose the defroster gets air to the windshield via the gap between the front of the dash/garnish and the windshield.
