Found 82 Cordoba drivetrain

Anybody know if a 1982 Cordoba 318, transmission, and rear-end will work in my 73 Swinger? It only has 25K and is supposedly super clean. It was rear ended and was totaled by the insurance company. The owner drove it in and drove it home. The body shop said it ran perfect. It's still in the car so if you all say it fits and price is right i'll check it out. Thanks again for all the help!
