‘75 Duster drivers side vent?

View attachment 1715515483
That’s why I asked the question. I have a 71 that has a circular opening in the left corner under the dash and that’s where the vent attaches. It’s not there on the 75. I see a hole on the side near the top where the kick panel would go. I though maybe the air from the cowel was routed that way. As you can see in the picture, this is under the left corner of the dash, there is no hole. There is a small hole above and behind the fuse box. (I couldn’t get a picture of it). I thought maybe that fed a vent in the kick panel. Ugly under there.
My 75 Duster has no driver vent. There is no opening in cowl on that side. Maybe cause it has AC- mine does..
