We are hunting this pattern but after seeing what eBay sellers are asking people to pay, we feel compelled to make a brand new better heater core for the Mopar: 3420577,  from your pattern.  Together, let's stop the madness.

1974-1975	1970 Charger w/AC	1970 Satellite w/AC
	1970 Coronet w/AC	1974-75 Fury All models w/o upper vent

	1974-76 Monaco w/AC, w/upper vent

We do not keep this heater core in stock & will need to fabricate it.
