Hitch Pin Replacement Question

1. It was me first opportunity for the vertical leap.
  2. Setting the treble rear duplex bearing as usual and tweaking the non-duplex
      section's down bearing is refined with vertical pins. Also the 
bass bridge cap
      was replaced with a taller one to accommodate the new hitches.
  3. Reasoning...economy (those bass hitches were a bear) and not wanting
      to get too far afield. It was a customer's piano in for re-restringing and
      action regrooving (read truck-like) correcting a previous rebuild.
