Can't find the list which was in any thread some month ago.
I have to install new seals in my Montesa 123. In were two sets of 35x47x7 any advice?

These blokes sell them and their mud scrapers as well. Seals on the bottom and mud scrapers on top keep the fine crap out Maybe Greg does all there sizes, I don't know. But these blokes stock it all.
They're bloody expensive but very good. I think you need 2 sets per bike. Ask so you don't get one side only

Thanks Vince and Rob, maybe it ist difficult. The original fork has two seals 7 mm length and a Seeger ring. I could change to one ring and a spacer or order the original? (dunno)
 
Its possible in the case of Laverdas to fit one seal and the mud scraper below the circlip BUT you need to modify the mud scraper so it will fit by grinding it down in size. I then added the black rubber cap as well. These green gadgets are steel encased in plastic. Its tedious but doable. Maybe your application won't need this or you make a spacer and only use the seal. I tend to go nuts and do all I can, overkill but that's me. BTW this full system is fantastic, seals very well but reduces stiction by lots.

The mud scraper can be discarded when fitting these seals to 1970s style Ceriani and Marzocchi forks. An alloy Spacer is available.

Details on how to use and fit these seals please view https://damclassicracing.com.au/55217048-1-fork-seal-35mm-skf-low-friction-35m/

The description has graphs of friction reduction when compared to the two traditional 7mm seals. (Also manufactured by SKF)

If you find a common circlip has been fitted to reatain the fork seal it is advisable to replace it with the OEM Snap Ring because the tangs of the circlip may contact and prematurely destroy the sealing lip. https://damclassicracing.com.au/50320251-fork-seal-snap-ring-for-35mm-forks/
 
I have a 1200TS with marazzochi forks they had two seals so machined a spacer the same size as one seal and got the correct sise seal from brookes suspension UK no leaks and works well
