Wilwood Proportioning Valve?
I have been told told that my proportioning valve has gone bad and since factory ones are hard to find, i have thought about going with a wilwood adjustable valve. This one.

From what I have read is that I would have to make my own tubing from the MS to the valve since the factory ones dont line up. I would also need to buy a flaring kit to flare the tubing. What I would like to know is how much tubing do I need and what connectors I should get to get it all hooked up. I have searched around and just wondering from others who have done this as to what they have used.
I am also planning on getting new MS and booster and all new lines to replace everything. Any help from anyone is greatly appreciated and I plan on going through summit for the parts if anyone has any part numbers as to what I need.
