UPDATE: I am still struggling with this issue. I would love to take this car to someone who knows (and is willing to work on) the body-related issues, but have completely struck out with finding anyone near me in Central Florida who can help.

I've attached a summary of the issue and what I have done so far to troubleshoot. If any of you are willing to give this a second (or first) look, you don't have to pour over the thread, just read the attachment. I will be eternally grateful to anyone out there who can help me.
