I was looking over the build sheet of my 81 GMC and found a couple of codes that I couldn't find an answer for. They are 30P and MX1. I did find one site that said 30P was a wheel color called Med. Adriatic blue and all the sites I looked at for MX1 was MERCHANDISED, TRANS, AUTO PROVISIONS. What in the world does that mean?
