Factory AC Dash Removal

Hi all

This 67 dart convert is my first Factory AC car.

I want to remove the entire dash as a unit.

I expect I will need to remove the registers attached to the bottom of the dash frame first.

Any and all advice is welcome.

There is no refrigerant in the system or coolant lines from the firewall Forward.

I will be pulling the steering column 1st no matter what.

Thanks in advance.
