The high mount light is what todays drivers look for and notice most.
We bought our 1st 67 notch in 1982. It was rear ended twice in about 6 years. @nd was a Triumph TR7 I think. Lifted the back of the fish and dented the fuel tank. I put a 3rd brake light in it. It was never rear ended again. So that addition was the very 1st thing I did to the notch we have today. bought it 2006. It hasn't been rear ended yet. I think the 68 B'cuda is the most needing. It has more reverse lamp than brake lamp.
