5) NO soft parts should be re-used. KYB diagram shows where to put the new ones.
Max, we actually did re-use the TOP rubber washer ( flat on top, cupped on bottom ) on all 4 corners.
BTW, Joe opened his boxes and his also have NO upper sleeves ! BUMMER !
I have approval to return my 2 that didn't have sleeves, but I suspect I might be getting replacements that also have no sleeves.
I will just re-use the OEM sleeves with a bit of drilling out as we discussed if this does happen.
