Fuel Tank Shield Insulator Hardware

Bought a new to me 2012 TRD Sport 4x4 a month or so ago and just now noticed a strange noise coming from underneath. Upon inspection, I found the fuel tank shield folded over rubing against the drive shaft. It appears to be missing the hardware to mount this shield. I have found the shield part number I think
7769704010. But unable to determine the hardware I need to make this right. Photos attached.

 

Anyone have any idea what hardware is used to fasten this shield? I'm going to check at the stealer this weekend if I have time.

 

This EXACT thing happened to me years back and scared the ever living shit out of me I'd broken something serious. I bent it over and haven't had a problem since. I wouldn't bother paying for the part.

 

Nice to know I'm not the only one! When it was bent over I'm like...how did this happen?! It was not easy to bend it back over without removing the axle. Thanks for the reply!
