Dash vent needed for Fiat dino coupe’ 2400

[Zolpidem]

Hello, I’m looking for the vent in the picture because mine is broken or a bit is missing, as you can see. Anyone any hints?
Thanks

Hi,

Yours is assembled or turned upside down. First check if the knob is still there on the other side, you may be surprised.

It seems the same type of eye ball vent as in an Alfa Romeo (several types). I do have two of those vents with an OD of 72 mm.
