Work continues on the interior of my '56 half-ton. I ordered a black headliner from Classic Parts. Not sure quite what I expected to get, but i ended up with a thin, black, more-or-less plastic piece with a 1/4" grid feature molded in. I kind of like it - i think it will look good in my cab. The question is: how to affix it to the roof? i would say it is semi-rigid, so it won't need a uniform application of adhesive like a cloth piece would. I do think it will need something to hold it up besides the rubber moulding.. any suggestions?
