So if I understand this correctly I should do
C4 had 35 tires 3.5 lift 1 inch body...... 4.56
AOD has 33 tires 2.5 lift 1 inch body..... more than a 4.56

I don’t understand what “way too tall” means on gears

Higher gear ratio equals “Tall gears”

Tall gears = numerically a low number.

Think of a tall person who only takes a few strides to cover a lot of distance.
Short gears is a small dog whose legs are a blur trying to keep up with the person walking along slowly.

... and surprisingly, even though they seem to be saying opposite things, both are correct. "Higher gear ratio" usually is in reference to picking a "higher gear" in the transmission or transfer case, like high range is "higher" than low range. But high range in a Bronco transfer case has a gear ratio of 1:1 while low range has a "higher number" of 2.46:1.

So to be clear people resort to different techniques. Some, like Broncobowsher did, get wordy and specify numerically higher or numerically lower ratios. But a really common way to distinguish is "taller" and "shorter" (or maybe more commonly "deeper"). And Broncbowsher's leg length example is a great way to visualize that. Or you can think about tire size, with taller tires letting the engine go slower at a given vehicle speed

5.13 is not the way to go here, that will effectively eliminate most peoples desire of an OD by making it essentially the same final operating rpms and speed as your current C4 only with the addition of a 4th gear. 4.56 is plenty for the 33's and if you are planning on more off road you could step to 4.88's but I run those with 35's and have no issues whatsoever.
