W126 1984 300SD.

i bought a guide rod mount kit.

the bushing that looks like a big ball joint.

however i had a lot of problems and ended up putting it back and not using it. the kit came with a bag of new screws and 2 captive nuts, for some retarded reason i broke these 2 captive nuts.

i wanted to go get this part put in by my indy. however i was wondering if i can just buy these 2 captive nuts somewhere. everywhere i have only seen it come in the kit, but i already have everything minus these 2 nuts.

i have a local mercedes dealer, is there a part number for this? thanks for any help
