NOS Delco wiper motor cam 4960408. I found it to fit 71-75 Pontiacs on the internet, but check your application to be sure. Grand Ville, Bonneville, Catalina, LeMans, GTO, Ventura etc. If you know others, let me know :)
Plastic, so a wear part, if you don't need it yet, grab it for when you do!
This is true old stock as it came from a dealership that closed it's doors in 76.
