@Toolman and @Ronman

Thanks for your answers and suggestions. That after market solution is for shure not perfect, but might be the alternative to stock.

Yes, that is definitely a Mercedes star, but the number is starting with 193, which is not a MB model range. As we all know 193 is a Crossfire specific part. Have also reseached for other better photos, and it seems to be 193.

We've checked if it's maybe a 163 part (W163), but the dimensions are different.

Also did some research on the development and for shure there are some Crossfire specific parts on rear axle that are not borrowed from some other Mercedes models.

@all

Thanks a lot to all that helped. And if there are other solutions or ideas, please let me know.
