I have a 1940 chevy 1/2 ton. Can anyone tell me if the nobs I have are correct for my truck. Door window cranks, front window, ash tray are rose, all in good shape. Ivory? for the defrost, heater these are cracked/crazed. I can read defrost but can't read heater. Would like to find replacements also need the chrome bezel's for both. Choke and throttle have black center with chrome around the edge no marking's different style- flat. Cig lighter has an amber center? chrome around the edge. Thanks for any help. Phil
