They definitely hold the o-rings, every rebuild kit I can find has rubber dust seals which I assume go over the top of these but hard to tell as I literally just had shreds of rubber left in mine. I’m hoping when I order the rubber parts that the tinnies are inside.
I think I’ve managed to answer my own question on where the “plug”/spacers go as I was just going off the fiche but the manual has a clearer pic. I still don’t have any but I’m sure I can get some nice thick washers, I can’t see exact thickness being an issue.
