Thank you! That was more and better info than I got from Suntour.
They sent me this:
“please see attached exploded views of what I think could be your fork. As you can see they are similar but not the same, you can’t really tell the difference between them from the outside. As far as I’m aware, there never was a DC98 or MG98 for that matter.
There are no specific user manuals for your fork and we don’t have the catalogues anymore, the fork is just way too old.
I hope the exploded views help.”
For future use of this thread as a reference, I’ll add the exploded views I got from Suntour
