Rear axle paint markings

[68bee]

I found this paint marking on my AAR Cuda's rear axle. I know its for the gear ratio but don't know what gear ratio.
Looks like 078 to me. What do you think an does anyone know what ratio it stands for.

Thanks

078 is 3.91
Can you measure the overall length of the 3 numbers? I'm trying to verify spacing.

Did any other markings still remain on your rear end?

Thanks.
What is the meaning of the 'V' at the end? is the 3-26 a date code?
I've seen some 'K' an 'X', etc... not sure what the letter means.
