i don't believe its legal to change your mileage to the the motors rebuilt mileage,,it should alway read what the car has on it, just note the mileage when the motor was rebuilt on a sticker so u know what the engine has on it, if u get a rebuilt cluster u can have the repair shop set the mileage to the closest mileage u can find, ie: last title mileage,,don't go any further back on it as u will be signing a odometer disclaimer form, that way if u lie about the mileage the shop don't get screwed and lose his shop or licence, and get sued himself, its a legal form for the shops safety. there are lots of ppl on ebay that repair clusters or sell rebuilt ones with the mileage u need it to have.
