Damn, this guy also swapped in the Evo braking system onto his 2G.

Apparently they will bolt right up if you use 99' model year and up Galant knuckles.

I pm'ed him about whether the Eclipses were 420A or 4G63 and what all was done to pull the swap off.

He said the rear calipers bolt up without any modification at all.

EDIT: Added a couple more pics. You can see the rest of his gallery at dsmtalk.com.
