Pakrat, graphics is what my wife does for a living and she has done many old trucks. She does both hand lettering and vinyl. I fact, she used to work at the Graffix Shoppe that 46 in progress mentioned. She would be glad to answer any questions if you want to do it yourself.
I think you could find someone to hand letter it in your area if you want. Find someone that used to race at Jackson and ask them who was (or is) hand lettering race cars yet. I'm sure there's someone in your area.
