I know iits not the most budget-minded solution, but there are reproduction headliners out there, and the backing is ABS plastic-much more flexible that the original material. I picked up one for my '84 Monte about a month ago. The company that I bought it from, upholstered it to match the old one, and it came rolled up in a long box. I haven't installed it just yet, but it looks like it should fit fine.
