Thank you! Was aiming at 30mm x 30mm so I was not too far off... 🙂
Carsten, are the black bows new rebuilt bows from Claus?
The shape looks correct. (The rear bow which are located above the rear window is more flat than the middle bow.)
The bows I bought from Claus was the opposite ( the rear bow above the rear window was more rounded, and the middle bow was more flat.
Maybe the template was mixed up during manufacturing of my bows as they does not seem to be correct.
