34 Instrument lights

[Ken/Alabama]

Still working on this 34 Roadster. Doing a complete rewire and pulled out the speedometer to clean and lube it. Question is , where are the light sockets for the speedometer? It has the window for the light but there’s no sockets or holders for sockets. I have another housing that has sockets but not sure what year it is. Thinking about mounting them onto the 34 speedometer housing.
