68 notchback headliner help please

The sail panel boards in a notch are a long diamond like shape. They are barely large enough to cover holes in the sheet metal. The headliner should have enough material to cover the sail panel all the way to the package shelf and under that board a few inches.
I'm thinking maybe you have the same problem I once had... fast back liner in a box marked notch back ( PUI brand ) but... if that's the case, the second seam / bow sleeve from the front would be in the wrong location as well.
