I received the '41 to '46 fresh up kit from Jim Carter and it was a perfect fit. After reassembly this speedometer runs smooth and quiet. Unfortunately the spindle has disconnected from the speedcup. I was able to repair that with some superglue, but I think the orientation is off, and/or the magnets are weak. I have another old speedometer that may use the same speedcup, so I may be able to swap parts.
