1969 B body dash pad removal

[1969CoronetR/T]

I have a 1969 B body dash that I picked up and want to swap some parts off of it to replace the parts on my R/T. I want the lower dash pad and took five or six speed nuts off but the top left is still hanging up. I do not see anymore speed nut at the top so does anyone know what is holding it up? I would like to take the lower dash pad, control center and instrument cluster out of it.
Thanks again
