Howdy I've got a 1985 g20 conversion van. The headliner in the cab area was completely shot, not just the fabric, but the mdf board as well, coming apart in pieces.
Any idea where to source a headliner board for the cab, or a template perhaps to be able to cut a new one? I could try to measure it all out , but there are a lot of subtle curves.

 

You might be better off converting to the older vinyl and bows style for a DIY approach.
