Wanting to know the name of the frame or part number that holds the bracket for the muffler hanger. Lucky it came off when I was working on it.

 

Here is an update I found the part I was looking for. The Hangar bracket attaches to the reinforcement bar. It is not protecting much if its corroding like in the picture. A new will have to do. Got to remove my bumper anyways since someone car scrape across it.
