Where to mount my valves

So I'm installing the valves and I'm stuck as where to mount the front valves. I'm running a 4 port tank in my bed, so they're not getting mounted ON the tank, I found a decent spot on the frame for my pass side, but it wont work on the driver side. I don't want to mount it on the outside of the frame, I don't really want to mount one up kinda close to the front and one further back. I'm open to ideas... Pics would be nice!

mine are mounted on the outside of the frame under my doors. You cant see them unless your face is on the ground

On my 92 I mounted the front valves to the crossmember under the back of the cab.

I'm gonna try this, what kind of valves are you running?

mount them to the rad support behind the bumper
