RPO code question..
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?

Re: RPO code question..
MX1 = TH350
I don't know what 30P is, but it is supposed to be a wheel color. 30P = WHEEL COLOR MED ADRIATIC BLUE (94)

Re: RPO code question..
I got one for you all....GQ1 rear-axle standard. What is the gearing on it? It is a 1981 2wd Blazer it has a factory tow package if that helps. I know I can take the cover off and figure it out just thought since we are on this subject mabye someone might know.

Generally it is going to be 2.73's for 81-87 and 3.08 for 73-80.
