After years of looking for a Judge I have bought a 70 and have a few questions to ask about the car and what are some of the correct parts to round up for those that are missing. Please keep in mind that I have never owned a Pontiac A body of any kind before.The first question is about the cowl tag I understand the WT1, M-21, D80 part,the the color is 06 06, what does the 6 mean? I thought that Orbit Orange was just O.Also what cars got the black rear spoiler? I need to find the right radiator, should it be a 3 or 4 core ? and is the shifter the same for console and non-console cars? I need to find the right shifter and handle too. I'm sure that I will have many more questions to ask. Thanks.
