so I was asking before asking if I need a press to install it. I got answers both ways, some people said yes, some said no. My experience is absolutely yes I didn't have an exclamation point so we burned the old ones and butchered these lol it goes without saying I have to redo it because a lot went wrong. One of the Russians sat backwards, one of the metal discs broke off the hammer and one of the rubber discs went missing. I was lucky enough to take photos before I started for referenceβ¦
