I've only ever used trial-and-error to get panel fitment right, but my last van (85 Chev conversion) used some neat tricks to eliminate some weird curves from the roof panels... hard to explain... I'll try.
The edges that run the length of the van? It had sheet metal curved into like a side console shape... a flat section that bolted to the side ribs, and then bent flat a couple inches below the ribs in the roof. There were spotlights mounted in there down the length as well as an LED strip. Then it had a curved bend about an inch long, then bent flat with the roof ribs... so the side profile of this long panel looked like a wave, but with flanges that screwed to the roof ribs and the wall ribs... recess created above for accessories! The result is that there is a straight line for "square" roof panels on the sides, and you only have to curve the front of the roof panel... plenty of surface to screw the sides of the roof panel down, as well as the tops of the wall panels.
Sorry though, I don't have measurements for the headliner. I just encourage you to think outside the box if no one can come up with a template for you.
Boy, am I jazzed right now about my early... answering posts with out answering the topic?
