I have no clue what subaru part # a rear wiper blade is for a 2005 wrx wagon. Any help would be greatly appreciated as all the replacement wipers will not fit onto the rear wiper assembly. Yes, I checked subarugenuine parts and such could not navigate to find part #. Also, any wiper blade after market companies act as if there are no rear wiper wagon available. I appologize just need to vent.
