Hi KitKat. I guess it would be helpful to know which refrigerator you have. You can still look for hinge replacement kits. This is just a link to a repair kit that I found by doing a cursory google search. I’m not sure it’s what you need but it might point you in the right direction.

and depending on where you’re located or they do also have Mail order you might try an RV surplus supplier. A couple I’d suggest would be Bontragers surplus or Johnson surplus they are both located in Michigan. Bontragers is always my first option for hard to find parts.
