I didn't like the look of mounting the control valve on the cylinder head of my flatty. On my 32, I mounted a 36-37 vacuum control on passenger side of the K member, drilled and tapped the clutch cross shaft to attach a lever rod to activate the main valve. Made a custom cable for the hi/lo shift. Works great and you don't see the control valve. Maybe you could do the same. I also have an original electric control set up that I am not going to use, if you decide to go that way.Whatever you do, you want to make sure there's a way to disable the valve if the clutch is not engaged. This way you will not accidentally damage the unit.
