Turns out both my 91 E30s came without rear floor vents under the front seats.

I went ahead and retrofitted them to the vert which was super easy to do.
Interesting that BMW went to the trouble to delete the vents and add foam back to the carpet where they sit.

They also capped the heater box on each side.
