68 Barracuda trunk/quarter panel transplant?

Hey guys! If you look at my other posts you'll see I'm a scatterbrained guy who's just starting out in the mopar world. My original Barracuda has heavily rusted out trunk pan, lower quarter panels, trunk extensions (I think that's what they're called, don't know terminology so take a look at the pics), and the back side of the hump where the wheels are that connects to the floor pan (please fill me in on terminology!).

I managed to acquire a second 68 Barracuda shell in hopes of transplanting good metal onto my original one as it has shot floor pans and is just a sheet metal shell. Any recommendations/plans of attack for essentially cutting and taking the back half of one car and stitching it onto the back of the other?

Thanks in advance! Feel free to laugh away at my hair brained scheme. Black is the car with the bad rear sheet metal, orange is the new donor.
