Please help. I got gifted a 1966 T855 tandem dump truck. I have no idea how to shift this beast. Has 2 shifters. First one is pretty basic, that second one is very strange to me. On the shift knob, lower left has a "U", lower right has a "D", upper right has an "O". Does anyone know what the who these stand for? Thanks in advance for any help.
