transmission bracket progress

I decided not to use the bending technique from the other day.  I started laying it out, and just didn't believe that I would be able to lay it out well enough with 4 bends to fit well.  And for something under the middle of the car I choose good fit and ease of fabrication over good looks.

Even so, Figuring out the order to do these many steps to ensure everything goes together took some reasoning.  Here are a couple pieces held in place:

 Here is the result of weld up (fit ended up perfect):

I had decided on 3/8 for the bolts to the floor, but reconsidered and went 7/16-14.  Unfortunately 7/16 is the only bottoming tap in my whole set (odd?) and I can't start the hole.  I don't have the courage to power tap on the lathe yet.  Here are the two holes in the DS floor and the two studs.  I will make a doubler plate out of 1/8 or 3/16 plate and weld it all in once my taps and other bits get here from McMaster:

 Here is the transmission bracket with the center three bushings welded in and ground down and one of the frame rail bushings shown not installed:
