Standard Differential Ratios?

Can anyone tell me what ratio would be standard in a 68 C-10 Custom w/327 and TH-400? If I counted correctly, I had about 1&5/8 yoke turns to 1 wheel turn. Doubling that, I come up with about 3:23/1. It's on another guy's truck, and I'm looking to buy it for my 61 3/4T for $100. Numbers are unreadable, and he won't let me open the case. No mention on the glovebox lid. Thanks in advance!

Standard was 3.07-1 which is about what you counted.
