It looks like what we might call the 'striker'.
A bit more detail please. Then I'll try to look it up for you.
Is this on the door or the body of the car?
Side, sliding door?
Rear lifting tailgate, hinges at the top, or twin doors hinged at the sides. If twin doors, which door is this on.
Edit: 2005 is a model change point, so need more info.
Car or Van
Full VIN would make it much easier. Don't post the VIN on here, send me a Private Message.
