FWIW
This will fit 96-02 4runners, 95.5-04 Tacomas and 00-04 Tundras with the 3.4 liter engine.
AISIN is the OE manufacturer of the Toyota water pump. Often times when I order them they'll have the raised "TOYOTA" casting ground off on one side of the pump.
Would be a great item for someone to have on the shelf as these are often a failure point.
