Just purchased 83 camaro got to looking and found that the mount for the differential to the body on the body is busted and hanging to the body. New to the site just see what my options are and what to do? Thanks

 

I'm guessing your control arm mount is torn from the chassis or is it the panhard bar chassis mount?

Regardless your solution is to have a competent welder inspect and repair the area. If it is torn away due to rust then that will be a different answer.
