So need a full float rear axle for my truck. Currently has the bombproof 14 bolt semi float. Axles are currently 3.73s, so want some 4.10s anyways. Truck will see mostly mud, but also whatever terrain is out there. Don't plan on rocks, there aren't any!!!!! I found all three in local yard, all need a little work, but kinda steering away from the 14 bolt. The way the bottom hangs so low, it gets hung up on everything. Yes I know that it can be trimmed, but don't really feel like doing all that, just for a couple of inches. Also looking for one with at least a posi. I know the 60 and 70 can get a T/L or P/L, but the 14ff only a Govlock, want something more predictable. Can't afford a Detroit right now.
