Per the ad: "Ran great prior to letting it sit for 14yrs I have not attempted to crank it just want it gone 383 w factory a/c Drum brakes are locked up from sitting"
To answer the question; those vents are not there on a non-AC car.
The "just want it gone" statement means someone could probably grab this one for $1500 or even a lot less. Put a $1000 in one pocket and start tossing the Benjamins on the hood and see what happens.
