Welcome! I know the Custom cab trim varied from year to year, but usually included trim around w/s, cab "flags" made of stainless or aluminum, cloth seat instead of vinyl, chrome grille/bumpers, sunshade for pass, armrest for driver etc. Chrome bumpers/grille were available separately, as was side trim. Steps had no side trim w/Custom option. Build sheets was behind seat springs, usually long gone. Hope this helps, Brian
