Yeah, that's the same area. Tomorrow I will see about removing the cowl and fender to get a better pic. On my previous 240z, I cut the roof off in almost the exact same spot the crack is in on the new 240z. Without a doubt, there is lead in that area. It didn't have the shine of sheet metal, but did have the shine of lead, a lot like in the picture at the end of my post and certainly looked like it was used as filler. I'll get a pic of this too. I poked at it with a screw driver, and like I said, it was FAR too soft to be sheet metal. It is, without a doubt in my mind, lead filler. I can't think of anything else it could be. I don't blame you for being concerned, and thinking it's a crack in the sheet metal. That's exactly what I thought too!
Anyway, tomorrow I will try to get pics of the area on both cars with cowl and fender removed. Thanks again for your input.
