The problem with markings is that many of the paint splotches and crayon marks assembly line workers put on cars they worked on varied depending on who was at what station that shift, how much paint was left in their tin, how ambitious they felt that day etc. From your picture it looks like at least some of your markings survive in good shape to document, so clean carefully and take lots of pictures and notes of what you find.
Otherwise you are just copying someone else's car. Which is better than nothing, but you can't say your car is exactly like it was when it rolled of the line copying other cars.
Certain markings like stenciled on part numbers and even the painted lines on the bottom of the gear housing designating what ratio you had should be consistent for all cars, but the other markings are not.

Hi Scott,
I'm new to the forum and also have a 1972 Challenger Rallye 340-4 with the 3.55. I have attached a pre-restoration photo of the axle showing the markings. Hope this helps.
Hey Vince I really appreciate this! It's pretty cool to see how each was treated differently.
However from my research the information presented by @JH27NOB is the most accurate way to go. I will put the paint daubs on the bottom and the part number if I can ever figure out what is the correct number to stencil on a 1972 E-body 3.55 rear end. Anything beyond that is a guess since no line or person had the same way of doing it back in 1972.
If I were a betting man I would put the X on it but that would be a guess.
I will add this photo to the collection though!
I am trying to get more photos taken during the restoration of my car. Hopefully they will show more detail of this area. If I get them I will let you know. I just bought the car from American Dream Machines in Des Moines, Iowa. Saturday I spoke with the previous owner who said that when it was sold to ADM he gave them a binder full of photos taken during the restoration. I just found this out and will call AMD today to see where the binder is.
that's awesome! Post them up so the whole forum can see what some of the original markings were!
Mine was a complete shell when it was brought in for restoration most is not all of the original markings long gone.
