I was actually doing some similar research as I've been using the Intrax lowering springs and KYB GR-2 struts for the last 10 years now and have some bad noises coming from the front.
Had my car examined and evidently my bump stop's, labeled as (bumper, I think) in the diagram link you posted, are worn out. The shop I was at is TireRack certified and they showed me the KYB part I needed, labeled as KYB Strut Boot. From the diagram it seems to provide the dust cover and the bump stop all in one.KYB also provides the strut mount piece, also listed on the TireRack page. Without seeing a link to the exact information you're referencing, I would imagine the Strut Boot and Strut Mount from KYB would be a complete set of parts, along with the actual strut and perhaps Camber/Caster adjustments pieces as needed. I might be wrong though, as it seems some of these pieces have multiple names and each person/company refers to them differently, so hopefully somebody else with more experience/knowledge can verify.
