82 92 Trans Am Owners
Those of you that own a 3rd gen Trans Am. Does your car have a vacuum reservoir to trap vacuum for the heater and air conditioning system. I have a 85 T/A and it does not have one. If so where is your vacuum reservoir mounted and what does it look like?

Not sure about it being for the air/heating system but my Formula has one located on the driver side beneath and forward of the battery tray. Looks like a black, plastic ball.

Earlier cars (not sure how early) had a log shaped one near the brake booster.

My '84 T/A (H 4bbl 305) has the same sphere mounted like Mongoose's near the horns. Not sure you can see it without being under the car.
