Rear Axle Code Brake Drum Decals

[Dave69x33]

Can anyone confirm if rear axle gear ratio decals placed on the face of the brake drums were common, and if the decal was red or black letters on a white background?

If anyone has original decals still intact on their drums, a picture would be great.

Also, was there not a practice of writing the code with a paint pin or grease pin on the bottom side of the differential when the axle was positioned upside down in the rack at the axle fab plant?

Thanks!

I don't recall reading or hearing that anywhere (not that it means anything!)...  Where did you hear or read about that Dave?  ie.   the source for the information?  I'd love to read it myself...
