Delux,
Look at the links page on this site. You will find many parts suppliers for your truck. Many have on line catalogs. Jim Carter of Independance Missouri has a repo headliner. As you will find with most if not all repo parts, They all take a bit of work to make work.
Reading your other post... I would get your truck running first. The Headliner should be a low priority in this stage of your restoration. Before you start taking everything apart, take some pictures. Work on your truck in a series of small projects. It is very eazy to get overwelmed.
Best of luck to you
John
