Does anyone know of a source for the diaphragm that goes in the windshield washer pump on a '64-'67 Skylark? I got one of the rebuild kits from the parts store, but it has everything BUT the diaphragm in it. The diaphragm in mine dry rotted and ripped into two pieces.
Try Zip Products. They are a resto company for Corvettes and will not have listings for Buick but most of this stuff is the same. They even have the white plastic nozzles for the fussy corvette guys.
