I screwed up, neep help

They only used the Butyl and not a lot of it either.
65ChargerDart, I guess I need to look at the trim a little closer before I go any farther. I thought the inside stainless was held in place by the clip but your saying its not. How is it held in place? I know the outside is held on with the small screws but was thinking the clips went on there as well. I better take a look at it tonight before I go any farther. Either way I need to get the remaining 2 screws out and I know im going to have a tuff job getting them back in! Do you have any pics of this assembly as you did yours?
Thanks Rod
