How do I remove the dash pad?

[parb]

Just started phase 1 of the restoration of my 72 GMC Jimmy.
Got all the interior out (seats, carpets panels) and most of the exterior trim.

I need to remove the dash pad. I got the 4 visible screws removed, are there screws from under the dash holding the pad as well? If so what is the easiest way to get to those screws?

Is the exterior trim on the doors and front fenders held by clips or are there screws involved? It looks like there is a nut near the rear edge of the door that holds this trim piece?

Thanks for your help!
