I've covered this topic in excruciating detail in previous threads. too much of hassle for Kirban's. it's been a few years since kirban's briefly offered SPIDs. ECS is company making the item. contact them directly with your request.

can only get one if you can provide a picture of the SPID you want duplicated. swap a trunk lid back in the day without saving the old SPID? Or buy a car missing the SPID? you won't get a legal replacement due to auto insurance/crash industry regulations.
