The door & quarter glass windows are the same between 70-74 Challenger and Barracuda but rear window is different. I believe much of the structural & mechanical parts are also the same between the 2 but some trim and body panels are different.

There is two different rear window packages, a very small one and the large.. hummm, I seem to disagree but it would be worth looking into
