I am trying to find a font that I used a while ago. it is italic and looks like the font that most race cars use as their number decals. I cant find anything!

Try here, I've seen several of these...

What category would they be in tho...

do you think I didn't try looking? I couldn't find anything

Sorry mate, but your question is like going to a book store asking for "a" book. If you had a sample of the font you want to find, it would be easier to help you, since not everybody is interested in racing cars

Do you need an exact match or only something similar?

As vague as the question...

Try Great Lakes, slant 15 degrees right/left: http://www.moorstation.org/typoasis/designers/curtis/pages/g.htm

Actually Dale Jr's # font is My Puma Oblique, then I believe its flipped 180 degrees then mirrored.
