#12 in the diagram below. See red marks.
NOS 1000669. Vacuum ball for A/C systems on cars WITHOUT K34 Electronic Cruise Control and without Olds V8 (Olds V8 without K34 cruise used the half rounded version in the upper left picture). Typically A/C cars with the cruise control had a single-port monster huge vacuum ball took care of the A/C vacuum as well using the 2 way check valve. This is the 2 port smaller vacuum tank (about 4" diameter). It's in line with the HVAC vacuum signal from the intake manifold. The ball is usually mounted on a plate that secures the A/C accumulator in front of the HVAC housing. It maintains vacuum signals for the HVAC flapper positions during all designed engine vacuum signal ranges.
Brand new, never used. Lived all its life between a GM warehouse and my smoke-free home. Popped the box open just for pictures. These live in a harsh environment and the mounting tabs are cracked and broken over the years.
$15 plus the ride from 29803. Even the aftermarket ones will cost you more. Sorry, check or money order. No paypal, venmo, zelle, etc.
