Not sure about the 2002, but in the 97-99 there aren't any connectors at either end of the ribbon cable that connects the LCD's to the circuit board - the small LCD's are bonded to the ribbon cable and the ribbon cable is bonded to the circuit board. Someone with the proper skill can replace them but its not plug and play (see link below).
If the 2002 has connectors at either/both ends of the LCD ribbon cable, then it would be an easy 15 min job to swap them. Maybe someone else can confirm how the LCD's mount in a 2002. Or you could open up your existing cluster and have a look for yourself before you buy a used cluster unit.
