Could happen. I've thrown away several 7 1/4 rear ends over the years. For what I build they are useless so I just toss them in the scrap pile. Everything I build gets a Dana 60 or a Ford 9 inch. The trick is that you have to be in the right spot at the right time to find someone who is tossing a 7 1/4. And of course, it has to be the correct one for you application.
