What is the OEM rear axle ubolt size?

The ubolts on my truck are 5/8 inches. And they fit just right into the trailing arm holes.

I bought a lowering block kit, and the ubolts are 3/4 inches, which do not fit into my trailing arms holes.

So I am thinking either they sent me the wrong ubolts, or my trailing arms are not factory.

The correct u-bolt diameter is 3/4". There must be rust built up in the holes thru your trailing arms.
