Sure you have. Big black box buy your feet on both pass and driver side.
I want to see some pics too. Never hered of a vent delet car before. Would be cool to see. I can get you some pics of my duster tonight if you want. It is all torne apart right now and I can get you some good pics of the holes. I would think your car should have them though if it had A/C and a heater it need to be able to draw air in from some where.
