The vinyl glued back on, using 3M's High-Tack Spray Adhesive. The vinyl insisted on keeping most of it's original shape, and to counter this the internal edges were taped down after painting to prevent slow curling and hopefully eliminate future delamination. The cut of the vinyl is factory original; that's how it looked originally. Not pretty, but it did the job.
Test fit of both headliner halves. That is not their original colour - they were white, as was clearly shown by the areas that had remained hidden. That's just 50 years of dirt, possibly combined with cigarette smoke, who knows.
Finally painted the halves with the excellent paint for vinyl used for the roof headliner.
Just an after and before view. Note how screw holes and top edges do not lign up. Welcome to quality control, 1960-style.
All three original headliners, roof and eyebrow, installed with their original vinyl. Very happy to have been able to keep them.
