David:
The upper door trims are pretty easy to make, for anyone even modestly possessed of woodworking ability, and without the originals as patterns. Suggest these parts be recreated in solid wood(s) of your choice. I did it for my coupe in koa, a native Hawaiian hardwood. The curved dash bits are another story.
A pattern for curved parts is going to be difficult to get. You'd need a flattened plan view, then a pattern for the curve, projected onto the horizontal plane. We'd all be interested if anyone comes out of the woods with such. As soon as I take out my dash I'll publish a pattern, but don't hold your breath. The dash bits of the last coupe I parted were so rotted that they fell apart in my hands, so I have nothing to volunteer. Though - I just thought - a pattern for the curve is simply a bit of 2D material scribed and cut to fit... hmm. That part may be easier than first thought, but what is really needed is someone that has a disassembled dash. Calling all such....
The "trick" is to create the underlying form, then get veneer stuck to the form. Vacuum bagging is only one way to go; you could as easily use sandbags or bags of water to press the veneer to the base. Even a bunch of spring clamps with proper cushioning will do it.
A great wood project while one is self-isolated from THE BUG.
