Hello Lou,
I haven't been able to get a good picture of the wind lace installed on the head liner.
As for the sail panel courtesy lamp location, here are three pictures. I hope they help.
This is an original sail panel. It looks like the hole position is incorrect, but it is NOT. I think that when the panel was originally installed, it was placed too far to the rear. I compared it to another original panel and the holes match up.
As you can see, the measurements are made from the top back corner of the panel at a right angle to the top edge of the panel and also a right angle to the back edge of the panel. The point of intersection is the center of the circle.
