Chevelle Wiper Motor Part - What is it called?

[SS427]

I would simply replace it with one from a donor unit. They can be had for virtually nothing and I don't recall ever seeing one of these solenoids being sold new. They are a little tricky to remove and replace but can be done with no problems. Much care has to be taken when bending the metal tabs underneath the face plate but it can be done. I do this on every frame off restoration we do.
