Upper front shock mount fix?

[C&C Chevy]

I notice the other day that my front end was bouncing around alot more then usual. I pulled the wheel and was just going to look for anything strange. The upper mounting hole in the frame appears to be hollowed out and the bolt holding it in place was loose. Not sure how big the mounting hole should be but mine looks bigger then it should be! Anyone else have this problem and how did you fix it? Anyone have pics of the proper mounting bolt with washers and nut? I think Pepboys just threw some larger washers when I had them replace the shocks awhile back.
