What's the best Hemi Orange spray paint? Can't find PlastiKote 226.

Same deal as "correct" b5 blue in 1970. Had an original paint 70 Duster car from one factory and another RR from a different and guess what... they weren't the same tone... so correct is nothing but a wishy washy term as the mix could be slightly different. Even had one of the gurus say the Duster was a repaint and not correct... ummmm yeah.. not right but OK.
