Screws for the dash trim are #8, chrome, domed countersunk heads mostly, except heater control used flat countersunk heads. Some of the head sizes used in Mopars were smaller, like a #6 head on a #8 thread. Glove box screws were a silver cad or zinc, button head, and I think 10/32 thread or something on the glovebox latch. All the other screws are sheetmetal thread.
Your dash pad should be the same color & shade as the other dark green interior pieces, especially the A-pillar trim.
