There iS no need for the broadcast sheet. This is an easy question but you are going to find it hard to duplicate the factory apearence.
In 1972 the tailpanel could have been painted two different ways. In 73-74 the tailpanel was painted only one way.
In 72 the Challenger Rallye was its own model. By that I mean if you have a Rallye, the VIN will start with JS23. The base Challenger in 72 had a VIN that started with JH23. In 73-74 the Rallye was just an option package on the base Challenger. Because of this, all 73-74 Challengers have a VIN that starts with JH23.
The 72 Rallye cars have thier tailpanels painted black. The correct black is called "organisol" and it has a texture to it. It is the same paint used on the Challenger T/A and AAR Cuda hoods. The area around the tail lights on the 72 Rallye cars should be painted with med/dark argent. That is a heavily textured paint that has some metal flake in it.
The 72 base model Challengers had there tailpanels painted just the opposite of the Rallye's. The tailpanel was painted med/dark argent and the area around the tail lights was painted with organisol black.
In 73-74 since there was no separate Rallye model, ALL the tailpanels were painted the same...just like the base models in 72. They should be med/dark argent with organisol black around the tail lights.
Now comes the bad part. The correct argent paint hasn't been made in years. A few companies still have some of the origonal stuff left but they only use it to restore parts that they sell. They don't sell the paint itself since there is so little of it left.
Totally Auto sells both light and med/dark argent as well as organisol black in spray can form but the argent isn't 100% correct. The light argent is way too light and the med/dark argent is too dark. Right now however, this is probably your best bet. Definatly go with the darker argent because the light stuff really looks bad on the back of the 72-74 Challengers.
My 73 is at the bodyshop right now and they are going to play around with mixing the two shades to come up with something in between. At the Mopar Nats 09, I went around and looked at all the 72-74 Challengers. I only found 2 that were painted correctly. One was a survivor car and one was restored. I had paint samples of each of the Totally Auto argent colors as well as a test spray of a mixture of the two. The mixture was very close to the correct color. It needed to be darkened up just a little. For now I would definatly go with the darker argent instead of the light.
