transmission and differential identification

[Lucas2208]

hey, i have two questions

1. transmission number: E6-TY856WN2CA which subies got this transmission?

2. when i look at the bottom from the differential i  see this number: 013 KN43.

in which cars are these differentials fixed in?

does these two parts fits together?

ive bought a transmisson swap set to 6 speed but im not sure if those parts fits.

my car is a impreza wrx 2004 uk version 🙂

Best regards Lucas
