axle code confusion...

[Big_Bad_E]

I have a 46 axle code and have found 3 different charts that only has a 46 on one of them which says that it is a 4.56 gear. On 2 of the charts it says a 45 code is a 4.10 and on the 3rd it says a 45 is a 3.55. I would have guessed my stock '01 Sport would have a 3.73. Can anyone give me a difinitive answer to this and perhaps a link to an accurate axle code chart, thanks in advance.
