Yes, it replaces the stock heater.

I did get a tube that's fully the size of the oval vents but its been cold enough I haven't been out there verifying where it fits if at all. The space is worse than I thought getting past the column and wipers.

Thought so. That's not what I'm planning, I just want the add-on A/C.

Honestly, I was thinking small-diameter (or oval) GVAC ducting for the driver-side vents.
