Most of those are parts to a ford f-250 airbag kit fits 2011-2016

I'd Like to Know:

This is a large set of items that I believe goes together. The bottom 8 pieces in the picture all have the same paint and coating so I am almost certain they are a set. The top 5 items in the picture however may be random and unrelated items. Focus on looking for the bottom 8 pieces and what items those are first, and let me know if the top 5 pieces are also part of the set. Regardless, I would like to know what these items are and what their purpose is, as well as what they go towards.
