Forget it. I tried to weld it several times -> it broke !

>2. Has anybody encountered similar fracture.

Yep.

>3. How to avoid the problem in the future.

Buy one which has a better mounting method. The new ones from Hepco&Becker
seem to be a bit better, cause the have a continous flap on these two
mounting points. AfricanQueens also offers a crash bow, but from the
picture supplied there you cannot imagine how it looks or even is mounted.

Achim

P.S.: Seems like we would have to change the crash bow every 30.000 km ->
insert an entry into the maintenance book :-)))
