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.

After I panic posted about needing this part I decided to go to my FLAPS just in case they might have something that would work. Much to my amazement they actually did have a matching part included in an inexpensive generic drum brake kit that covered multiple Mercedes models (but not w124's according to their parts db).

For future reference, in case anyone else is dumb enough to lose this part like me, the kit I bought was at a FLAPS with same name as a well known valley in California. Its details are:

3363 (assuming this is the FLAPS part number)
