What ratio do I have?

Below are pics of the diff on my 59 Super 88. I pasted this in from my thread in Major Projects.

Question: Note the number lightly stamped on the diff housing. Is it a six or a nine?? A six would be 3.64 to 1, a nine would be 3.23 to 1. Not sure of the intended orientation.

Thanks,
John

The axle code is on the axle tube,passenger side???
Your looking at the Julian date of manufacture,=January,5,1959.(A59)
The number on the carrier I would say would be a 9.
You can always mark the tire and turn it two revolutions counting the pinion rotations.
closer to 3 rotations would be the 3.23,near 4 rotations,the 3.64.

Thanks Nasty! Didn't notice anything on the axle tube but I didn't really look there! I think it's a nine but the book really isn't clear on this.
