The silver faced clusters came on 03 XLTs. Of course, FX4s and LIIs are also XLTs, so they got them too. The Tremor and Sport Trac clusters are similar but they are white.
The black clusters are the same for 2WD and 4WD. The white and silver ones have different cutouts and indicator lights between 2WD and 4WD. To tell the difference, check carefully on the far right for the 4WD and 4WD LOW light cutouts.
