The piece  that holds the door from opening too far came off and i can't figure out where to pry with a screw driver to fit the metal piece in the spring part. thanks

Timmy!Feed it through from inside the door.In other words pull it through the rollers out through the slot in the door.It will only go so far and the rollers will hold it like the door was in open position.Then put the pin back in to hold it to the body.
