My 2004 Ford Everest has a cracked speedometer sending unit. My local FORD dealer has a monopoly and has priced a new OEM replacement for $596 US dollars. Even though they are the dealer the vehicle was purchased at they will not give me the part number in order for me to try to order from another country. The only number on the unit itself is 4D12 . Do you know how I can find this part number? The VIN is MNBC34D404W109913
