Looking good. I can't tell from the photos, are you using the locating dowel sleeves on the TDI and the dowel pins on the bell housing? Those are critical for keeping everything in alignment. When I made my own adapter plate I ended up getting a set of Toyota spec offset dowel pins for the bell housing side of the plate, then when assembling everything I mounted an empty bell housing and transmission case onto the engine and used a dial test indicator to adjust the offset pins and minimize runout.
