I did try to suckle, bone dry.
I went back outside and played with them a little. They definitely feel like screws that were drilled in from above and went too far. Not far enough to breach the liner but enough to create those impressions. I can only imagine what's up there and why it was done. I guess I'll have to pull the liner down and find out.
[MENTION=46025]HokieRunner[/MENTION] I saw an older post of yours on a search about this and I was about to pm you as you mentioned being familiar with the process. I'll go open the sunroof first to see what I can see and then start from the front as the next step. What's involved in pulling the a pillar trim once the handles are off? Yank?
Do they get harder when you play with them?
