Early Delay button on top of dash
Does anyone know what this knob on top of dash is on my 70 GTO, could this be T81 headlamp delay? It says early delay with 45 degree of movement. The evenness of I dentition made me think it was original. It is not listed on my PHS docs, it is a high convenience option car.. I was planning to have dash redone and will skip this if aftermarket. Hopefully picture is attached.

I would say that is aftermarket. The Code 672/T81 option was a 60 second timer delay that turned the lights off automatically.
