The upper pivot tube will be welded in and it will use the stock plastic bushings to keep it simple. I appreciate the axle pics, they'll be useful for reference when that step is reached. Got a bit more done this evening:
I thought the body assembly was almost done, but totally forgot that the upper part of the body needed to be cut down around the upper pivot to clear the pedal box. The horizontal bandsaw made short work of this otherwise PITA step.
This shows the body with both the balance bar and the pivot tube & bushings.
