72 Monte Carlo Heat Question

[jyardgirl]

Hey guys,
Recently acquired a 72 Monte Carlo and a Big block but have a question about the heater core function. I assume the car is a non a/c optioned car as you can tell by attached pics anyways, where do i find my heater core hoses (if i even have a heater core). Perhaps heat wasn't optioned? I've searched and cannot locate hose bungs like on my 71. where do no ac cars draw hot coolant is my main question.
