Whenever you're shopping steering wheels for your vintage Ford, it's important to think about not only appearance, but driving comfort and function. You want a steering wheel that feels good to hold in your hands. Some look good, yet they feel just downright flimsy.
Another thing to consider is whether or not the steering wheel's styling jibes with your restomod. Some vintage Fords and Mercs don't lend themselves to some of the more outspoken designs we see today. Another issue is color. Does the steering wheel's coloring match your Ford's interior and exterior? Woodgrain works well with nearly any interior theme. But, make sure it ties in with any other woodgrain finish that may exist inside. If your interior has a lot of chrome, the steering wheel should possess chrome as well. Brushed stainless works well with chrome and brushed aluminum. Matte black or monochrome should tie in with a like treatment throughout the rest of the interior.
Remember that "tasteful" stuff we keep rehashing in the world of restomod. Do your own thing with everything, including steering wheels-just keep it tasteful while you're shopping and building.
