The best way is to just buy the whole cluster, then it remove the outer dash bezel, tilt the wheel and 4 bolts, 1 plug and your in. I put a platinum cluster in my 04 and love the chrome lined guages. Several nice looking clusters on ebay and at jpcustoms. (forgot on line address)
Sometimes you can find a platinum lense cover cheaper.
If you have to do a complete overlay the was a tool to remove the needes from the pins but be careful the pins are easy to bend. I think jpcustoms has a tool.
For the esv gauge cluster, did you have to re-calibrate anything as far as the speedometer and the odometer? Does the current mileage transfer over to the new cluster? Wanted the platinuim gauges on my 04.
