I just got home and was gone from dark to dark today. I hate short winter days. My SE has the indicators in the same location as yours' Matt. I know it was built in 69. I don't remember what month. I would think that this was an early design location since the other one I have seen on 70's is in the same location as other years. If I remember correctly, you could not get the indicators on a '70 car with the magnum hood. I'll check with Barry and see what he knows about this. Here are a few pics I took in the past about the indicators. If you need more pics let me know. I will be home for half the day tomorrow.
