Heater ac assembly parts - help sourcing parts

[Samwoo81]

Hi all
I have a Westfalia nugget which is a mk7 transit.
We have an issue with the heater always blowing on our feet.
We have today taken out the glove box and discovered that the wire from the blend door is not connected to something else.
Looking at the following thread have helps me identify that we have a part missing. I have circled below.
I have found the spring and the long wire connecting rod in the ash tray.

Does any one know where I can get the circle parts?

This is the thread that helped me id the issue.
