1968 barracuda factory color question (red)

The car looks great in pictures, however the lower rear 1/4 panels are garbage, as well as some cracking in the filler. The car was painted years ago in a back yard by the PO so there is dust in the paint as well. I love the color but I will never know the paint code due to the fact that the PO is deceased. I think the matador red is a little to dark for my liking. I don't know what to do. I would like to confirm the factory color by the fender tag. Where do I look, I am a chevy guy and am used to seeing them on the inner fender on the drivers side under the hood, cant find the one on this car. thanks for all the input.
