79 W72 car would be the same as 1978. It would look just like the pictures above with two resonators under the rear seats. Single Cat, with a Y pipe leading into the resonators from the outlet of the cat. Only difference I can see compared to the photos above is the y pipe did not have a ball connector at the cat like the system in the photo. It was a square 4 bolt flange just like the front of the car. Otherwise dang near identical imo.
for what its worth my 80 Trans am has the same resonators & tailpipes, but the Y pipe after the cat DOES have the ball connector. I am not sure what cars have it that way or when it started, but the W72 cars didn't have that ball connection. Hopefully that makes sense.
