Gray dash is standard color. All new trucks came with gray dash.
Korean war stopped the use of most chrome on the '52+ trucks. I believe this is true for the '53, so the proper grille would have been painted body color with Thistle gray inner bars. The bumpers and hub caps would also have been Thistle gray. Door handles and windshield divider would have stayed chrome/SS and a few other misc. parts. Interior knobs maroon plastic.
Buy the new patch panels and cut them up to get the sections you need. Way easier than fabricating panels and the costs of patch panels is reasonable.
headliner should be maroon cardboard if I am not mistaken. There are others on the forum way more knowledgeable about the different years than me. I have a '52 and only focus on getting the color correct for the '52.
Good luck.
