sjvcon Report post Posted November 6, 2019 I have some Southwest Trailer Brake Drums. Brand new with bearings. Fit the standard 3500# Axle Setup with the larger interior bearing and smaller exterior bearing. Stud pattern is FIVE ON FIVE. This pattern is critical and WHY I AM SELLING. I screwed up when I ordered them … switching back and forth between items on Amazon and when I finally decided I hit the order button … fully thinking I was looking at the Five on Four and a Half I had been looking at ALL DAY. Whoops. Mounted them before I realized I had screwed it up. These would cost you $50 a piece new. I'd like $50 for both … but I'll entertain offers. Color me stupid … teach me to flip flop from website to website comparing. Knew the spec … botched the order. Share this post Link to post Share on other sites
