Early swingarm bearing conversion

Here is an original harley round swingarm, a very coveted item. However, they came with a wack bearing system, using timken bearings and no spacer sleeve between them. They actually recommend (in the old manual), to use a "fisherman's scale" to set the preload on them using pivot bolt torque. WTF?

My solution is to upgrade the hub area to accommodate new sealed bearings and a spacer sleeve, like a new wheel hub. Here it is... and the best part is, you can press out the entire assembly and go back to the old style if some hipster offers to buy it from you!
