Guys
I think I may have found the issues without pulling any plastic trim. Usually rattles come from lower places on the car and we pick them up in our ears. With that being said...I took the bottom bolt that holds the seatbelt to the bpillar. When I removed it, I stuck my finger in there and realized there is a metal-on-metal layer that is not welded together. You can put your finger in the hole and make the tin metal sound with it. I stuck some 3M tape in there and around the bolt where it holds those pieces together and that seemed to have stopped the tin metal sound issue. It has taken 3 weeks to find that crap.
