1) Based on the latest pics, looks like the clock is orientated properly. It looks like the correct corner is at the pcb dot position, but you should be able to see the difference in real life.
2) Opto looks correctly inserted.
3) Mosfet looks ok.
Try it and see, at least plugging into the computer, while you wait for any unit for the other side. If you've already installed the software.
