I believe that some others also have the painful problem of broken noses from the A-pillar covering. In order to get a grip on the annoying problem of the hanging panel, I printed a repair nose with the 3D printer and glued it with plastic glue over the remaining stub. Is simple, keeps great and delights the owner of the V8.
In the attached picture you see on the left an original nose and on the right the repair of this.
If you want to have one, two or three pieces, you can contact me.
Alternativ, da man es nicht sieht, kann man auch den Bärendreck nehmen womit die Heckleuchten montiert sind. Hält bei mir seit Jahren uuuund es bricht nicht wieder wenn mans doch mal demontieren muss.
