Broken hinge lock

I'm attaching pictures of my problem. My hinge lock piece has broken off and now my door can't attach to the track to open and close it's a TV stand that can be closed up when not in use it has a sliding track inside.

My door is 7/8 thick and the hinge that I need will wrap around the outer part of the door when it is open. Please email me back if you need more pictures. The picture with the small little piece is what broke off. I have also attached a picture of the track system that it is to be attacked to. and a picture of the way it wraps around that door.
