can you change the mileage on them to match your old one so that the reading is accurate?

 

why? You can put in a gauge cluster and go to dmv tell them you had to put in a new cluster and they can retitle it with the milage you had when you changed the cluster and the milage on the cluster so when you sell you do some math and you have the correct milage. Something along those lines.

 

or, depending on the car, you can switch out the speedo.

 

Depending on the guages and the year, they can reprogram them to read your original mileage.
