Hello everyone, it seems no one has covered the different dates and serial numbers specific to XU-1's, so I will start it off, based on what seems to be the original gearbox for my XU-1, this was rebuilt in the late 80's or early 90's, I think it is a 899 ratio cluster and has the XU painted in yellow.
