I'm having trouble on finding the quest MQ102 (Before the Storm) on the Creation Kit. Only MQ102A and MQ102B are shown, which, I believe, are defined by the players initial choice between Hadvar or Ralof.

Note: I've only opened the Skyrim.esm and Update.esm files, and another modded file (Which I was using to have a Heavy Armor version of the Studded Armor Cuirass), on Creation Kit.

I can't seem to find the way to change the item reward, given by Jarl Balgruuf, the Great, as soon as the Dragonborn gets to Dragonsreach, delivering the news from the Helgen atack.

I managed to do it to another quest, though. MQ104 (Dragon Rising), at the very beggining of it, on stage 40. I've set the reward to be something of my liking.

I'm trying to make Balgruuf reward the player with the so known "Dragonborn" armor set, by giving him the Banded Iron Shield and Studded Armor, both with light and heavy versions, depending on the character's repective skill levels.

It would be great if I could change the Studded Imperial Armor and Steel Armor too, which are rewarded as soon as the player informs the Jarl. I would very much apreciate some help! Could anybody point me at the right direction? Don't know what am I doing wrong.

[EDIT]

I managed to find the problem. It's probably not set as a "Main Quest", because I found it with the search field.
