That's just the rock ring, the marlin service kit calls it the half moon plate.
From the Marlin kit description:
"Please note we do not include the metal split ring nor half moon plates because they are not serviceable parts and are recommended to be reused by Toyota."
I still need this part.
I can buy a wiper kit at the dealer, but they want something like $50 per side, and I already have the felts and seals and everything else.
Thanks for the input.
