Dash vents

[Gizmo327]

just recently noticed some dash have vents in the dash on the passenger side above the glove box and ashtray and others do not. was it a certain year that the change happened?

 Cars with A/C have vents in the dash, non-A/C cars don't.

Yea....all years of 1970-74 E Bodies had the vents in the dash if they came factory equipped with Air Conditioning only. No A/C meant no vents in the dash.

Thanks. Based on pics below I am guessing the dash got replaced with a AC dash since I don't have a build sheet or fender tag.

What does the firewall look like ?

hard to get a good view as the a previous owner relocated the radiator overflow tank to that location

Yup, for sure only the dash pad was swapped out at some point.

So you're saying that the drivers side had vents but the passenger side didn't?

The drivers side vent would not be in the dash it would be next to the heat & ac controls

No, his pictures say the opposite

 In an AC car, the passenger side had vents in the dash pad and the drivers side was in the heater/AC control panel plastic dash piece. In a non-Ac car, there were no dash vents at all. Vents in a non-AC car were under the dash frame and blew down on the feet.

Got it . . And agree.  Told the vents are getting harder to find.
