Alright, like many guys around here, i got shafted and got a focus without a tach. Ive been trying to get one on ebay with a tach, but clusters w/ tachs with about the same mileage for an 05-07 are hard to come by. Here's my thought: since you can split the clusters into the front half w/ the glass, and the business end of the cluster with the needles and all, im thinkin that maybe you could swap the front part from one that will fit the 05-07 (since thats where the mounting points are) and the back from the 00-04 and just put them together. My concern is that the part where you wire it into your car may be different and not be able to read the duratec computers correctly. Any ideas to as if this may work or not?
