So, the garage is in charge of that... but I also have a problem...
We received the new crash limiter but it is not exactly the same than the old one
For the broken area, it is normal...

But the real difference is about 2 additional part glued on the box. These parts are normally used to guide the cool airflow to the radiator.
On the new crash limiter I received, this 2 "extensions" or additional brackets/flanges are missing...
and Opel (Yes, I'm French) don't know anything about this flanges... (and in fact, don't know anything about this car... )
So, to illustrate, just have a look on the following pictures...
I found this picture on the net and I have circled in red the 2 flanges I don't have on ny new part

and detail pictures:


So, my question is the following:
Is it normal that I do not have these 2 glued flanges on the new crash limiter I received? If yes, what if the ref of this? Because I need them to rebuild my car…
