I was hoping this could be for a two-speed rear, but can't get it to move. It's out of the '58 Chevy 40 Series Viking which was only a-ton-and-a-half... not normally equipped as such to my knowledge.
I'll probably have to pull it apart, but thought someone here might be able to educate me about what it is.
