Lots of u-bolt info in the search but not specific enough. On the 84-85 axle, the factory truss makes the bottom of the housing square. Some folks run a 3.25" u-bolt vs. a 3" because the 3" sits funny on the axle.

My question is this: I am having custom u-bolts made for my u-bolt flip. If I had two square bottom u-bolts made for the long side of the axle, should they be 3" or 3.25" wide?

Am I overlooking something simple?
