Troy, You have a T/A Challenger. The front valance was obviously handled differently than a Challenger without the front spoiler. I have not investigated that area or type of vehicle so I don't know why or how the differences developed within their assembly process. Some of your "oddities" might be explained within the T/A build procedures.
The TA challenger front valance procedure should be the same as any other challenger. The front spoilers were placed in the trunk with instructions for dealer installation, thus no need for an assembly line change. The dealerships didn't always follow the instructions well during spoiler installation resulting in varied spoiler location. So far a copy of the factory instruction sheet has not surfaced.
For a spoiler bolt to have paint under it, that black on the valance must have been applied after the dealership installed the spoilers.
