Still confused about my rear axle - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I can't figure it out. What gear ratio do I have?
It's a 3600 so I figure it's got the 4.56 rear end. But no matter how I try and figure it by rotating the rear wheels and counting. It always comes up with about 2 3/8 turns on the drive line. Tried turning each wheel, and just turning the drive line. Each time it's 2 3/8. Not looking forward to pulling the cover and counting the gears, but I may have to if no one has answers.

Does this look like the stock axle? I know its a Chevy 10 bolt 8.2 or 8.5.
I found only one set of markings, can anyone decode them?
Thanks
