I got a new front bumper and upon mounting I realized I couldn't get it to not sag a bit, even though it was mounted properly on the plastic slides.
While looking for pictures, I found an image in which there appear to be some extra mounts on the bodywork that I don't have.

Could anyone tell me what these are, and if every BX has them? I'd really like to get my bumper straight.
