Steve and lambrain- Thanks for looking for those pieces for me. Much appreciated.
velocipus- Not really much more to say than what I've already posted.

The biggest thing is welding on brackets to the frame for the disc brake set-up.
Good luck with it and if you have any other questions, feel free to ask.
