Looks like your code is QQ1, which is Dark Red Poly. PPG/Ditzler code is 71476, which might get you a cross reference over here. I actually used PPG paint for my Challenger, but it is expensive. The only reason I went for it was I wanted an exact colour match to original Panther Pink. I saw a car in the US whose owner had verified the PPG to an original painted part on his car.
The sample that even PPG had over here in the UK was not correct - I ended up getting the formula from PPG in the US.
So.....what I'm saying is don't rely on someone listing the colour on their books as proof it will be the same as original. However, you can get them to make up an aerosol and you can check it's the same as your original paint (like inside the boot or somewhere untouched).
Alternatively, you may not mind if it's exact, as long as you like it.
Or - you could paint it black!
