How did the factory get the headliners in?
I asked the same question back then and don’t recall ever getting an answer. My guess is they used a press and steamed the fiber board into the correct curve radius. The shape might hold using the process used in shaping a cowboy hat, but on a much larger scale???🧐
I do know the headliner installation for my ‘46 wasn’t nearly the hassle experienced for the ‘37. I was able to install the ‘46 fiber board liner solo using pads some wood props and squeeze clamps. The curve radius is not as sharp, which likely makes the task easier too.
