I'm having the same problem. I can't help right off, but here are two things I have run across. What make the piece difficult is that the manufacturing process including first silk printing the black lines on flat anodized aluminum sheets, and then stamping the piece to get the rippled finish. Second, a few weeks ago, I ran across a 60 rag that really made one drop to your knees. The rear aluminum trim around the tail lights is a grown up version of the 61 dash pieces - anodized aluminum sheets, silk printed with black strips and then stamped to form. The owner said a shop on the north side of Chicago restored the pieces, and I could not tell them from excellent NOS pieces. The problem is I can't remember the name of the shop who did the work (Senior moment). I hope I run across this car again.
