Back in April I ordered wiper motor and arm from LMC. They did not have the arms after weeks of waiting I finally found the arms at Dreamers (rods and pickups). Finally months later I get around to the install. I unpack everything and find that the arms where they attach to the motor has like a octagon shape grommet and the motor has a plastic grommet (round) on each short shaft where the arms attach?? If I remove the grommets from the shaft the octagon shape will go over and fit on the shaft.then the transmission retainer clip and gasket will fit back on. question ? do I have the wrong wiper arms?? does the grommet supposed to be removed from the shaft?? Anyone experience this? of course LMC has no tech. advise and dreamers are looking into it and is going to call me back.
