49er, Good eye on those details. There was black around the fuse box (which is the case on most of our cars, later 280 SL's perhaps not), also black in the corners of the firewall, under the hood bumpers. I have sent a note to Tom H at the Classic Center, but no comment. I am trying to get a better list/understanding of what was included in 997.
Just checked the La Jolla concours site, 8-10 April 2016 is what is posted.
