Thanks for all the love guys.
Like Rusty said - that is just for the fluid reservoir (non-pressure side). I stupidly forgot, in my 15+ trips to NAPA and Home Depot to buy two of those clamps, so I just had to rummage around my garage to find one. You can see that a zip tie holds the other end of the 1/4 inch line. Either way, zip ties would have been fine for a long while anyway. I plan on going back with another worm clamp - no need for more expensive T-bolt style clamps.
Speaking on the terms of the fluid reservoir - The reason I couldn't shorten the tubing at all is that the 1/2 in to 1/4 in fitting I made was so long. Turns out that not many, if any applications in the world at all require a barb fitting from 1/2 to 1/4 inches. I am looking into purchasing a new fluid reservoir that already starts at 1/4 inch so I don't need any unions or such. It's something to note - simplicity is better. The less unions/fittings you have, the less places of failure and leakage! Even though this is the non-pressure side, less is always better.
BGTV8, I do believe this would be dead easy on a RHD car, if the ABS module stays on the left side. ^^
While I have some time at home, I wanted to shout out a thought. I brought up something in my original research thread that some people seemed interested about, and it's something I'm heavily considering:
I'm debating putting together complete kits for this master cylinder setup for sale. As this is my prototype, there are many improvements that can be made to make the setup more professional and easier to install. Also, if this progresses further enough, I will definitely contact AK and figure out something.
I was thinking that these kits would include EVERYTHING, including the master cylinder itself. This means it would come with a professionally-manufactured adapter bracket (most likely precision water jetted), all stainless-steel hardware (clevis, bolts, nuts, etc.), pre-bent-and-flared brake line, a new replacement fluid reservoir and tubing, and all brake fittings. You would receive the main unit pre-assembled, like you see in the original post. My plan is to also take my car apart again - and test every single kit I would produce, so I could guarantee that the kit I sent out is working perfectly. Of course, this will take some time and planning!
I could also include an instruction manual, full of pictures and descriptions on what to do and how to do it. As for tools, all you need are basic hand tools, and preferably a friend. Or, a local shop could do it as well without too much trouble.
Like I said before, if I were to re-do this prototype and make a finalized version, I would know how to avoid lots of headaches and missteps I took in making this work. I also want to keep testing my current prototype and make sure it works for many miles to come, under any driving conditions.
Anyhoo, let me know guys! It's something I'm really considering offering to the370z crowd! I know that this install has really evolved beyond a simple DIY, so I figure I can help put something together and we can all be happy. I'll also try to find time later by the end of this week to sit down and post some pictures detailing little niggles and stuff about the install and whatnot. Also, if there are any questions or anything I missed, please let me know!
