I looked at the 99 V6 cluster actually a few of them the diffrence it theres 2 torx screws holding the plastic on and the housing is shaped diffrent slightly but they all will plug in and work 4 or 6 cyl ones only problem is the V6 the speed will be off ,also 2 door and 4 door are diffrent as the door ajar indicator will have 2 extra doors on it ,and 98-99 are interchangeable 00-02 the temp gauge is controlled by the BCM and won't work right so if looking for the settl grey one it's 01-02 2 door EX V6 you would have to swap the circut board to make it work right and keep your mileage . if buying on ebay have them take a close up picture of the plastic as the V6 ones have the 2 torx screws in front bottom it's a 2 door Lx,Ex V6 only . the 7th gen will fit with very little fab work only major problems is electrical connections or lack of as all the gauges are feed from a databus direct from the ECU also the VSS has a diffrent pulse rate .
