Holy guacamole. I have a reason to update. My man at work was afraid of the rear charger bracket. Too abstract. I took it to Yoda and he reported 45 minutes of setup tapping and shimming. Apparently it was placed on the table like so and a long end mill swiped it down. I asked for .275" to be taken off. .250" for the plate and .025" for gasketry.
As you can see here, without a gasket the bolts are off-center. But who cares, it will work!
Next step is to get this threaded in the plate and a clearance hole thru the bracket.
