I was surfing the threads over the weekend and a member (from NJ IRRC) had posted a photo of the hood of his GC with an arrow pointing at the demarcation line. I even remember he said he had to take the photo at a certain angle to be able to show the line.
For the life of me I can't find that thread no matter how I search. Silly me for not subscribing to it at the time.
Could someone (or the member who posted that image) point me in the right direction?
