The second attachment shows the plastic support as 163-323-02-20. After talking with the shop foreman at the local dealership, he was unaware the plastic support was able to be purchased seperately. They have been replacing the entire assembly (torsion bar bearing - 163-320-00-73) at $170. Order availability for the support is scarce, (197 in them in the US) so if you need them at $18 and some change, apiece, you might want to rush to order, or you'll be buying the entire assembly.
