Broken interior in my Superb 03

[pettern]

Hi guys! This summer I have lent my car to my brother, as I have been driving taxi all night and asleep all day.

When I now have gotten the car back I see that he has managed to damage a few minor components of the car, he has suddenly not been taking good care of it :(

The damage that irritates me the most is the broken "blowout valves" for the blowout in the middle of the backseat (see enclosed picture)

As you see two of the "bolts" are broken, which means that I cant regulate the unit to turn up or down.

Are there any suggestions for how I can fix this problem, and if possible where I can buy new components?

Thanks in advance, Petter

The whole vent needs replacing, either from a dealer or breakers, it is possible to change the individual slats but it's a lot of hassle for the cost of a new unit.
