jmoore - PPG is probably going to be you best source/go to for answers on your paint mix info.
One thing I recall is many of the paint companies in the early/mid 2000's revised their paint mixes due to chemical and pigment changes/restrictions and the resulting colors didn't turn out the same after conversion.
Here's a link to
PPG 73840 1999 Viper Red. It doesn' seem to match up with any of your paint data above.
Hope you can find the answers you seek.
