Thanks a lot for reply guys, I should like to agree with you to keep and let repair the wing for a lot of reasons. On the other hand I have seen a moment ago that the wing behind the soldered on lamp housing has a clear compression. You can't see it too well on the photo but it's clear to feel that there's a pointy bump.
A look inside. I'm not sure if this compression is new where the Y-branch goes through.
Finally a picture of the out of sight wing above the wheel.
I would very much like to keep the wing because I'm afraid that a new one will never go so well with the car as this old one does. Ok, maybe one has to dismantle it to dengel it but it would be better than a new one, which still has to be cut up...
