I have been trying to find some paint for my car to paint the spoiler the same color as the body. The tag in the trunk of my '87 spider says "Blu Medio Metallica AR370." I looked up both Stellar Blue Metallic and Blue Medium Metallic and they are numbered 371 and 370, respectively. I think you have labeled your paint wrong. It is either Stellar or it is AR370, but it can't be both.
