Yeah you are right you have to change the speedo unit in the cluster to a 140 mph unit, still those plastic light directors must change with diffrent years because the 140 mph unit's did'nt even come near to some of the bulbs, all i know is mine was not what i expected and the faces were not the prob. (hold a flashlight behind just the face and it was perfect) But once installed and i saw it at night i yanked it out the next day,
I've had it out like 4 times and it as good as its gonna get,
great in the day but at night it looks x-tra ghetto

ps the actual swap is pretty easy & strightfoward
pps what kind of wiring problems everything plugs in nothing to wire but clean all plugs as i had a bad connection and the needles fluctuated on about removal #2
