Since I have been off work and layed up with my foot in a cast I thought I'd mess with some visualization tools for selecting wheels for my truck even though thats quite a ways down the road for me.
Found this website that has a very easy to use interface. Use their "Visualization tool. It only shows a half ton pickup for 1951 but it will do. You can adjust your ride height wheel manufacturers, styles, and diameters.
