Dash mounted splitter/range valves

Hello it's my first time posting on the forum, but I've come through here numerous times in the past for different information. Not sure if this is the correct forum for this thread, but today I was wanting to know of anyone that has relocated their splitter and range valves from the shifter to the dash. If so, what air switch/toggle/model number did you use? It's for a 1988 Peterbilt 379 with the 15 speed overdrive. With it being a 15 speed, I don't use the splitter at all so I figured I'd go with the hotrod look of a ball type shift knob. I know the air lines are 5/32, but is there a compatible air valve of that size? I was told before it was an easy job to do, but didn't get any detailed instructions. Appreciate any help and advice.

 

That's what I was worried about when doing this. I could shift the thing in my sleep, but you know sometimes you have those split second decisions or a brain fart.

 

Ahhh 10-4

 

Rogers on that

 

I appreciate the tips. I have a buddy out of Louisiana that used to own this flatcab 379 with a stand up sleeper called Old Number 7 that had the same set up I was asking about with an 8 ball shift knob, and I just thought that was the coolest #### thing in the world when I saw the truck.
