Fiddling with alignment of the main transmission.  Fabricating spacers.  Aligned everything.  Measured gaps and now fabricating precision spacers.  First was the left side.  The gap between the mounting tab is 0.103 on the outside and tapers to 0.089 on the inside.  The tab has a little tilt and the casting is not exactly level-flat.  Roughed a blank on the lathe.  Fashioned a holder, then faced down to 0.103 and drilled out the center hole to 5/16”.  Finally hand-sanded the tilt from 0.103 outside to 0.090 inside and fit to ship.
