I would have to go through my 15th edition hemmings almanic again but it appears the only places I have found was "the wiperman" who rebuilds them which theres not much to them just a few gaskets. Would like to take it apart to clean out the old dried up grease and oil and use fresh.
But I will check the book again though just thought I would put this out there if anyone has seen them before online
I checked Hemmings almanac I got and under wipers the only places pertaining to vacuum wipers listed are rebuilding or NOS companies that sells NOS units. Didnt see one selling parts. Guess I will just have to try some wd40 sprayed in through the opening and move the linkage back and forth to clean the old out. Just pray that nothing is messed up from age so I dont have to spend $108 to have it rebuilt.
