Thanks all for your comments and will to think with me. To keep the truck like a 1945 looking truck will be on top of my list. But my affection to WW2and the US part of it makes my lean to have this truck a part of my hobby. I added a picture below of my intention. This because I have to do some welding on the doors. I don't have a nice original paint. Nor a great aged patina. So if I paint it now, I can also paint it in the future. It's not a big project.
As for the speed. I am by far not a speed maniac. My previous car was a 1940 Buick Special. That had a torque tube so I had no affordable options. I do drive long distances to events, so cruising speed is something I would like to improve.
As for shipping to the Netherlands, I do have a contact in New Jersey that can ship for me by container. There are a few options I know of but don't know if available for the pickup:
overdrive different gears in rear axle different gearbox at mentioned above
