Engine Bay Sheet Metal Rubbing On Control Arm

Just bought this truck as my first car. Needs some TLC. I was looking at the upper control arms and the gaps between the sheet metal and the control arms are uneven between the left and the right side of the truck with the right side having half an inch and the left rubbing against the sheet metal from under where the battery sits. I noticed that the piece of metal jiggles up and down and I noticed some of the screws are missing. I don't know what type of screws go in there or how many places screws are supposed to go.
Can anyone help me find out what type of screws belong or what I can do to raise it to stop moving and match the other side? Thanks.

 

I'm looking at this on a phone but if the UCA was ever replaced that is likely just the remnants of bending the sheet metal to remove the bolt.

 

Yeah, it has been removed several times (not by me), but I'm trying to figure out what screws go in to hold that piece of sheet metal up a bit better, because it droops and hits the UAC versus the other side which is nice and firm and has plenty of room from the UAC.
The sheet metal I'm talking about is in the pic below.

 

Where's the engine?
Was this truck wrecked?
Look at the apron near the battery and see if it's cracked.
Look at the core support mounts.

 

That's just a picture from google to show what sheet metal I'm talking about. The engine and everything is there, I just don't have a picture. The truck had an accident, but all the damage was done to the frame which has been replaced. I'll check the apron near the battery and check the core support mounts. I thought it would just be missing screws because this truck has been tampered with.
