I have used donor parts of a large number of cars to my 1987 Peugeot 205 CTi. The mk2 Renault Twingo has been added to this list. I have joined the Twingo-dark side.
The window rubbers on the doors of these 205 convertibles shrink after 3 decades. Badly. New rubbers are not available. Junkers have the same issue. So, you have to be creative. We have created a Twingo-205 hybrid window rubbers, and they fit!
