A/c recirc. Air door diagraphm - 66 442

Does anybody know what the part number for the diaphragm. This is a two stage unit that can be seen in the engine compartment right next to the vacuum leads that go through the firewall. I have the service manual and the assembly manual and I cannot find the GM part number. Mine has the whole plastic piece broken off the unit at the metal crimp. Also if anyone also knows where to get one or has a used one that functions and works well I would be interested in that also. Thanx for any help.. Bill

Here is a pic of the unit I need.. It is referred to as a "Recirculating air door diaphragm" It has two vacuum ports, and controls the air door inside the A/C housing.
