Spoon Twin Blocks EK > EG?

Hey guys,

I’m looking to purchase a pair of Spoon twin block setup off an EK with the intention to install them on my EG.
The caliper’s have been machined to eliminate the use of a 3mm spacer between the knuckle & rotor.

Would like clarification on a few questions;

Is it as simple as just swapping the rotors, caliper and caliper bracket over?
Will the caliper bracket have the same mounting for the EK / EG?
Will it be more ideal to swap the entire upright assembly (knuckle)?
I’d like to avoid the above method as the EK knuckle is taller than the EG.

Any advice is appreciated.
