In my correspondence and here on the Forum, the question is often asked as to how one mounts or installs a combination valve on their car. Some bolt it down. Others try different mounting procedures. While doing some research, I found how ABS mounts their combination valves to their master cylinders. I have pictures of two ways. The first one is the "hanging" version and works very well, but I like the second way much better. It is very neat and tidy and out of the way and tucked under the master cylinder. It is the way I would like to install mine, if I have enough room under the master cylinder. Here are the pix.
