With this handy kit, you can make your own numbers and class letters. Just download and print the appropriate class letters and numbers, then print them out on your home printer. You can either tape them to both sides of your car, or use them as templates to cut out magnetic numbers. Just be sure that the final product is in a contrasting color so it can be read. (No white on white or silver on grey, for example.) All the files are Adobe Acrobat format, so you will need an Acrobat reader to use them. For a free Acrobat Reader, click here
