Hi Kurt ,
For just the line roller I guess you can just contact any Shimano Service center and from your location , it's a matter of knowing where the origin of most flight into the country , I heard in Shimano USA is very good in their service works .
I got my drag washers for my old 1998 Stellas from Jack Erskine , all the spools of my old Stellas sport carbontex drag washers , as for the grease you can get Cal's from the same source .
Jon .
