Looking for part numbers..............
Crank Balancer Bolt 12557040
Piston Ring Kit 12533558
apparently these numbers in my manual are incorrect
Ring Kit, Piston (Standard) - 12533556
Ring Kit, Piston (.250MM O.S.) - 12453325
These are definitely the numbers in the parts manual, the ring kit ones may have changed or else just are not often listed in online catalogs, but dealers should be able to figure out what the new numbers are from those.
