Steve,

These are all good ideas. I was kind of leery about posting paint codes and serial numbers, as there are people out there selling books with this info in it, and I'm not looking to step on anybody's toes. But the more I think about it, the more I realize that that information is somewhere in the public domain, and should be where it can do the most good. 

I have some paint codes here that I can add to the site, but would be happy to add the ones you have as well.  Here's what I have:
