I'm missing this part of the parking brake adjuster for one the parking brake assemblies on my 87 300TD (see pic below). I'm not sure what it's called so I'm not sure how to track down a new one.

The parking brake kit comes with a new star adjuster but not the sleeve spacer thing it goes into.

I found part# 1244230050 for a W210 model, but I haven't been able to confirm whether it would be same as what is used on the W124. The fact that the part starts with 124 make me think yes, but hoping someone can confirm.
