I am installing a wood headliner in my 1952 1/2 ton panel truck. I thought I would post my progress. I am using pre-finished maple. I supported the headliner panel with 2x4's and added another board to create the arc I wanted, and then I attached bevel cut trim pieces to the edges to support the headliner. I then removed the temporary supports. I posted pictures at the following site https://picasaweb.google.com/barthhc/Headlinprog?authkey=Gv1sRgCMG2o5Hvxd-OpwE#
