Decals for Conrail to CSX update

A greeting to All. This is one of the first times that I write on this forum, I’ve always read all its interesting threads.
I’m searching for decals to update locos Conrail to CSX, after their merger.
Thank You

I’ve received today july issue of Model Railroader and I’ve read an article on it on how to change factory applied locomotive lettering. I think that It is the solution to my problems.
