Brakes with the Respeed conversion kit, engine bay fuse boxes, transmissions, engines, leading ignition coil from the FC for 2GCDFIS... Heck you can swap the front suspension from the FC if you have some time, and well the ability to do it. The rear suspension from the FC can swap as well. Keep in mind FB's are a solid axle and FCs are IRS so you need ALOT of fabrication ability.
Other than engines, and transmissions, not alot is 'plug and play' but it can be made to work.
