The 90 525i M20 that I've got has intermediate size pistons in it, 84.06 stamped on the top. The rings are worn and the end gap is 0.8mm with normal range 0.2-0.5 end gap. So I'm trying to find some intermediate (or 00) size rings to put in it. Does anyone know a good source for these things? Patrick can get me some genuine ones for forty something dollars per cyl, but I want to see if there are any cheaper options.

Thank You
