I got my 66 washer bottle from this guy: SixPackFrank Editor's Note: Me too! - on Dan's advice.
Ken Stobel got his from Fellwock's for $39.00
I have the nozzle and hose kits for $38 and the washer bottles for $59. The 66 Pump is unique in that it is separate from the bottle. At the moment I do not have a source for them - anyone know of any??
