Green piece is original oil seal and top out bumper. The spacer is the raw aluminum piece with the o ring on it between the green seal and the red piston seat.
Hi i know its been a little while sice the last post but maybe i get an answer. Where do you get that spacer ? How thick is that plate ?
That's the part number for seal kit. Seems a few places show them but it sure ain't inexpensive. Could also give a shout to MarzocchiMark on here, he may have some of those seal kits
If you want to go for not oe marzocchi/skf part there are likely a few different wipers that will fit, it's just a press in wiper, just need the dimensions of it and should be able to get one at a hydraulic shop or can find online.
