Dana 60

I’ll definitely go with the lighter 70’s one then. I am mostly am just concerned about being able to drop off my current rear axle, put this on, throw on tires. I’m a super newbie to this, and I just want to replace my nearly blown 7.25 as easily as possible on a budget.
Most of the bigger Dana's have floating axles and 8 bolt wheels. As said, the tubes are huge as are the u bolts. They don't work with your stock hardware. Just because they are Dana's doesn't mean they are the one you need. A 8 1/4 would be fine for you or a 8.8 Ford rear. Those take some modification as well to make work.
