VW Passatt's lateral beautification

The lateral beautifiers of the VW Passat at the bottom carry some plastic that withdraws to put the cat, these embellisants have broken me, I do not know if you have to change the entire section of embellishers or you can change only these, waiting for an answer receive a cordial greeting

Hello.
I am sure that if you ask it in spare parts of any VW dealership, they will get you out of doubt before.
All the best.

As you told me I have been in the concessionaire and effectively sell them and have told me that they are easy to assemble so I have requested the two being the cost of approximately 12 euros, I think it is the cheapest piece that my car takes because every time I take it to the house it is fearsome so I will choose to take it to a trust workshop, thank you for the reply Reyeric
