Differential debacle

Hey guys, I'm trying to get to the bottom of what gears to order for my old taco.. I'll be slapping on 33's and the gearing already seems way too tall as is lol. I've been reading endless charts on the codes and they don't all seem to add up.

For example they state the first letter, A: means 7.5" ring gear.. B: 8" ring gear. But everything I find for my B02A code says its 7.5" 3.58 2 pinion open.

Wondering if anyone who's dealt with that code can confirm lol. I've attached pics of the charts I'm referring to

 

7.5 is front ring gear
8.0 is for e locker
8.4 is for open rear diff
