Are you talking about the Belleville washers like in the OBX? I do have some actual Belleville washers I ordered to replace the OBX ones that were suspect. I don't know if they interchange with the OBX ones. Can you post a picture or give me some dimensions of the washers needed? Also how many are you looking for?the A568 has a quaife diff with 4 spiders but the washers are cracked if I leave them out the slop will be huge.
