They are pretty generic. Saw an artice in Popular Mechanics a while back about how to clean 'em; I think Toyotas are fluidic so I'd pop the pissers out and soak them in white vinegar (if you are 1/2 Italian like me or greater you will have other kinds around which will not do your pisser any good to put in!

) for several hours. See how that helps and then go to Advance or Auto Palace where they have the "HELP" parts (new little shit like door handles, cranks, pedal pads, most of it seemingly to fit '77 Ford Grenedas) and look for windshield pissers if they are still like an old man with a prostate the size of a shot-put.
