I was reading through the July 2002 GM High Tech Performance magazine and they discuss a brake perportioning valve bypass for supplying full pressure to the rear brakes that was made by Ron's Custom Auto, but I can't find them on the web anywhere. In the magazine they list a website, but it doesn't seem to exist anymore and any links I find online are dead ends. Does anyone know where to get one of these or how to contact Ron's custom auto??
