Help identifying random bolts?

Hey guys, I just bought a used 2016 TRD Off-road and after I got it home, I noticed these bolts in a Ziploc bag in one of the storage compartments under the rear seats. I know it's a long shot, but any chance somebody out there could help me out as far as identifying where they might have come from? The truck has a TRD Pro style grill, so maybe that could have something to do with it? Thanks in advance for any help you're able to offer!

 

Looks like trim bolts for mud flaps most likely( black ones) and Upper Control Arm bolts but that’s to short to be those

 

Those are the differential bolts they removed to install the diff drop. They have longer ones in right now.

You likely have a level lift. Top hat spacer on the front.

They put spacers on the skid plate too, so those are the old bolts that aren't long enough.

You're good.

 

Bingo on the long bolts

 

Wow, y'all are awesome! Thank you so much. As a reward for your hard work, enjoy some truck porn!
