Rear leaf spring shackle rubbing frame??

Today I went to swap my leaf spring bushings to get rid of the squeak. When I got under the truck I saw this.



The shackle and bolt are grinding against the frame. Part of the shackle is even shaved off. How can this happen? How can I fix it? The leaf pack is stock with a 2" aal.

 

bent frame or shackle mounts

 

Take a picture of the whole hanger and frame

 

Hey guys, thanks for responses and sorry I didn't get back sooner. The problem was band-aided with a washer to space the bottom but the bolthead still rubs. The problem is I bought these shackles from a member who thought they were OEM - they are actually longer than OEM and don't fit like they're supposed to. I need to find OEM shorter shackles.
