Is there anybody out there?

I was thinking some more about the brake system and the parts I will need and had some questions:
1. What diameter hard line should I use?
2. Can I use aluminum tubing?
3. Are residual valves usually flare fittings or AN?

I have also confirmed that mounting the underfloor brake booster/pedal assembly will require some significant fabrication.

Thanks in advance for your help, and I would still be very interested in pictures of a similar setup.
