You can get a guaranteed Type 3 Shell from Quest B40:

Which you shouldn't have any issues unlocking & completing provided you have Maya (and I strongly recommend you get her and level her up anyway, she's very useful)

You'll find the map is pretty easy if you have the type 3 shell, especially if you can get the boss to 60HP without it. Throw it on probably your Haruna.
