Maybe this site can help you out. http://mmcdetroit.com/ICCA/References/Inspection_Marks/#pop01
On the left hand side of web page under ICCA references is where I found the page I referenced for you. Lots of usefull photos of factory markings there.

This is an OE gold Challenger. It looks like it is a 3.55 sure-grip by the markings...3 white(for 3.55) and 1 orange(for sure-grip).

The chart also looks to be correct for 73 as well. I found two yellow dots(2.76) on the bottom of my center section after soaking it in EvapoRust.

that's what i need to see that mopar action article was perfect thank,s alot not that i will be able to buy or restore a hemi cuda EVER again - LOL but im keep this picture on my computer for references the 12-6 and the 12 7x are date codes ?

I think they are date codes. There is a date on the center section when it was assembled. THere is also one on the housing when the assembly was put together. There are no date "stamps" on an 8 3/4.

On mine, I reapplied the paint marks and then used RPM over the entire center section to keep it from rusting. So far it's holding up fine.
