Dash removal

hi everyone, i am a new owner of a 70 charger 500 and i am trying to remove the dash but getting stuck. got all the screws off but seems like there is something preventing it from coming off. seems like there is a pin holding it in place. and i was also trying to remove the dash vent on the driver and passenger side as well and i can't get it out because the lever for the flap is in place i tried pulling on it and it would not budge, left it in place and thought i would ask you guys out there for help.. thanks everyone..!! hope the explanation is clear if not just PM me and i will try to be clearer..

dash frame?there are screws under the windshield,and it has adhesive under that,also couple of bolts behind the kick panels

As noted above. There are several screws at the top front of dash frame that are under the front windshield weather strip. Remove window glass, rubber seal and screws. Also one screw behind each kick panel. You have to remove the steering column as well or drop it down out of the way. Good luck!
