Where can I find the heater control vacuum diaphragm for a '79 TA w/AC?

Roughly behind the glove box and radio. The two 79s I have at the house dont have AC, so I looked at the 72 and cant tell exactly where since the ducting is in the way. You will have to pull the ducting or the glove box insert to get to it, both wouldnt hurt, just be careful 30 year old plastic doesnt like to bend.
Performance and general repair tech. Traditional Pontiac V8 is my specialty, as well as automatic transmission repair/diagonossis. 2nd gen speciality, and with the addition of the 98 Formula 4th gen LS1 I am getting to know them real well. Holley and Qjet advice as well.

Chalk mark restoration and date codes arent my thing. W.O.T. is my thing..

Is it strange to have 9 firebirds?
