What is the best material to use to form behind the seat where the gas tank was? I see some good pictures of the finished project but I need some help getting started. Bending the radius and how to finish off the top are my biggest concerns.

ABS plastic sheet, It bends easily and does crack while working it like acrylic does. A little heat on it and it bends nicely. It also hold the fabric well when you cover it.
Get the 0.110 thickness. Its about $25 for a 32 x 48 sheet.

If you want a kit call Roddoors.com talk to Blaine. They have a headliner for about $229 that fits with minimal trimming, it can be left black or painted or covered.

That panel in my 53 was done with waterproof panelboard (sometimes called chipboard, I think?), which is another traditional material to use for these kinds of interiors. I'm told it can be sewn onto, which is a benefit. Something like this: https://actionup.com/shop/panel-boards/
