Cleaning the distributor off an 84 280E Euro that has sat for a few years, the thing was VERY junked up. When trying to clean the top half these sleeves (two are in the photo below) finally came loose after a bath in cleaner when spraying them didn't have much impact. I noticed I only have 5 and the 6th bust have jumped out when trying the spray method. Any idea if replacements are available for model "0-438-100-069" distributor?
