Whats my gear ratio in this gm 12 bolt???

I bought this GM 12 bolt from a guy for 20 bucks. Couldnt pass it up cause the price. So I got it home, cracked open the case and counted the teeth. RING 43 AND PINION 13. My problem here is I can't find this count on the chart I use. So I thought maybe one of you guys could help me. Thanks. The chart I have is all I have. See below.
Never crush'em. Restor'em or recycle'em. The payoff is always worth it in the end.
