That VW stuff all looks pretty simple and very easy to draw in any cad program. Be brave and give it a try, I think you will suprise yourself. I doubt if the manufacturers will give you drawings or permission to copy, but there is nothing to stop you doing your own design. If all else fails, send me a few rough sketches of what you want - sizes, materials etc and I will do it for you, but you will have a far greater sense of achievement if you do it yourself. Good luck. G.
