Finally getting to it!!! 1970 Duster 340

I spent time today working on cleaning up my driveshaft. I originally soaked it in Evaporust to get all the rust off. The shaft looked good but pitted. Today, I worked on sanding the shaft to get rid of any remaining pits. I'll need to take the driveshaft for rebalancing.
I saw to shadows on the driveshaft from the factory paint marking but unfortunately no traces of paint color. Does anybody have pictures or information about factory markings on a 1970 Duster 340 driveshaft for an automatic car?
