This is an NOS original Frigiking HVAC Faceplate with the 5.75 inch wide plastic vents.
This is approximately 20.5 inches wide x 3.5 inches.
It is the model shown in the operation manual and lists it for the coupe and cabriolet.

The left corner sustained damage which the plastic can be repaired and the black rubber pad can be heated up to soften it and reglued. After this is repaired and mounted the crack will not be visible.

You’re basically paying for the plastic air vents which are not available.
