Well, what's wrong with this picture, Spridgeteers? You can't bolt in the master cylinder with the box bolted down, duh! So shortly after I proudly took this photo I was removing the box. I decided to go ahead and reassemble the master and put it all in "to stay". The reason you can't bolt in the master is that the rear bolt goes directly between the opening in the firewall. I was just going to "rough in" the master to help with installing the brake/clutch lines.
