Looking for the font of the Gulf GT40's Number

[ranhammerR34]

Hey Graphic Arts and Image Editing Stars! I need some help... I'm looking for a font to replicate the number of the Gulf sponsored GT40s of the late 1960s to put on a car for RFactor. If anyone knows where I can download or get the font for any program (I have paint.net btw), and use it on the vehicle, I sure would a appreciate it. Thanks! --- Randy
