Dash paint - gloss level

Can anyone advise me on what is the proper gloss level of "black paint' for the dash in a 1970 Duster... It's due for a repaint and I don't know what gloss level of paint to get. Currently it's almost "flat" but that could be from years of sun bleaching... The drivers and passenger doors are currently a gloss black..

Any advise and or photo's would be appreciated...

My Duster is original and the dash is flat .. door panels are gloss
