they 100% go on with the locating washers. sometimes the tabs get bent in a little from the arms being adjusted/tightened, prying them out a wee bit helps. the fit in there is very snug and a little tappy von tapperson with the deadblow is a-okay for install. if you gotta reef on it, something's wrong.
So.....and I'm not arguing here, just posing a question. Why were they not used from the factory? Of all of the upper arm bushings I've replaced, not a one had those washers originally.
