Looks like you may have accidentally altered those part numbers (should be 8-598-928-00 and 8-598-928-01, notice the second number is a "9" and not a "2"). Anyhow, the service manual lists part# 8-598-939-00 which has type markings NX2631//A4S. What markings do your two have on them? I show them all subbing to 1-453-189-11.
