Front clip and doors, front seats, antenna, dash (speakers different), V6 front brake setup, glass, front mudflaps, both bumpers (rear will require changing the mount and end caps), bouncy seat base if there, rear door, brake drums and shoes, and small miscellany are what will be interchangable. Grab the front diff and CV's if you want to upgrade.

Rear axle is different, everything behind the front doors...
