Hi, I am looking for this part Door Lock Actuator Motor - Mitsubishi (part number 5715a728) however I am at a location where this part is not found. I have found though a part that seems to be the same, but with the part number A047218. By looking at the parts they seem to be the same. I also found ebay ads with both part numbers but some salesman told me they are not compatible while others said they are. Is there any way for me to confirm such compatibility?
