Actually knowing the current ratio isn't that important. What's important is what it originally had in it, because I'm attempting to maybe swap in a 3.90, and the kit I'm looking at only accepts 3.08 rear ends, or 3.23's, or anything bigger than 3.42... or some numbers like that...
Are there any other ways to find this out than the code? Such as cracking it open? If so, what exactly am I looking for?

You'll need to know the 3 digit number cast into the carrier. But this could of been changed also.
#671 was used for 3.08-3.23 with 28 spline axles. If you use the newer richmond style gears, this is the carrier you need. If you have used gears or maybe NOS ones, you could follow these:
#588 was for 3.42 and up with 28 splines: this one if using factory 3.90
#673 was for 2.56 and 2.78 with 28 slines
#672 was for 3.42 and up with 31 splines
I could be wrong, but this is how I understand it.
