I have an SM465 that came off of a tow truck that I bought. I intend to use it as an upgrade someday. Anyway, it has a drum on the back where the U-joint would bolt up to for the driveshaft, and I was told that was a parking brake. But I don't understand why it would be on the tranny instead of on the wheels.
