Finally getting to it!!! 1970 Duster 340

I found markings on my 727 tranny after I cleaned off 44 years of grease and road grime. I have not been able to find info about their significance. I suspect that the colored mark was used to identify the speedo gear size.
The color was very faded but appeared to be orange on close inspection. I tried my best at duplicating both marks tonight.
