well to keep it in perspective, you will tinker with the adjustment and then never mess with it again. I put mine where I did mainly because I could jump from the distribution block to it and then back to the original brake line with no cutting on the existing lines.
I sound like I am selling the adjustable ones, but really when it comes down to it you can dial a car in better with one than the standard ones ever did. Differences in engine weight, tires, and such make every car just a little differnet, but there was only one valve? Its not like the adjustable ones are expensive. My setup is a little dirty, but going from the rear brake line at the distribution block to a proportioning valve and then jump a line to the existing rear brake line makes it so you would in effect not be cutting up too much on the car and could go back to the original one when the time comes. The blue "X"s indicate the where the original brake lines and the "jumpers" hook up. I would say that it would not be all that expensive to have a shop create a jumper for the rear proportioning valve and then "nice" looking jumpers for the valve (nice compared to my butchered setup).
