Apologies I was rushing. The pic is a door catch mech. The oblong loop seen in the pic is missing the clip as it snapped. I had one on the mech I bought today but it's gone missing in the grass, with no hope of finding it. I need to try the stealer to get a clip but I need it to be as late a model as possible to have any hope of them stocking it.
It's really hard to lock and unlock the door without it. I'd rather not spend 20 bucks at the wreckers as they won't just sell the clip, where as new the part will be $5 or less. Basically I need to find out what is the latest model that use the same or similar type of mech and hope the part is still available.
