I recently heard a story about a local car builder, a true legend around these parts. Anyway, he wanted a certain number plate for his 32 Ford so he collected enough 32 plates to cut out the numbers and letters, weld them back up and metal finish both sides. That's commitment! That's a show car builder! That's awesomeness!
