Consider this a "parts" rear. It was drum to drum when I picked it up the other day. Drums rusted to the brakes. Destroyed one and don't feel like messing with the other. Bottom 2 bolts on the cover won't take a socket, but I got it opened enough to see inside. I see no broken teeth. I do not know the gear ratio.
If you want it, come and get it. No shipping. Located in Manchester, MD.
It's got some moisture in it, but it's not a clump of rust and wants to turn.
