I'd like your opinion on this one. Looking at the attached AIM page, my question targets the seal shown in the lower diagram as item #7 which is a mastic type of washer. Are these on all 5 speed nuts and this single view is an example for all, or do you think it pertains only to this one screw stud with the attached clip. I ask this because I have seen some kits on eBay and notice they include 5 mastic type of washers. These look to be in addition to the main cover channel adhesive.
