Removing air horns and adding train horn

Not looking for more volume.
1. They were leaking water in on my head.
2. Kind of thought they were ugly up there.... Prefer the clean look.
3. The covers that go over the opening rattle in the wind and keep me awake
4. I would mount them out of sight somewhere but they are to darn big

 

The clear coat was peeling too. Since I had all the stuff off anyway......

 

Any ideas on what I should put over top of the headliner for insulation? Looks like it had open sell foam originally but it's all gone now.

 

You could mount the air horns under the bunk and out of sight (open to the rear of course). Google closed cell foam insulation, Hush mat, Dynamat. Go from there. You should have dropped plastic over the steps, tanks, and wheels. IMO

 

Looking good rank. As for headliner material, you can use regular foam like what was originally up there, which can be purchased at any fabric or hobby store. You also can use the foil backed sound dampening insulation also. Kind of your choice, and how much of a hurry you in to finish up.

Kind of spendy, but been told this stuff works fantastic not to mention keeps your cab way warmer in the winter and cooler in the summer. Know guys that have installed this stuff in there headliner , and the thin sound dampener inside the firewall of their truck, and the thing is like riding in a car almost. Pretty amazing.

 

As to why so loud. When I am forced to honk at someone I'd like to go ahead and scare the bejesus out of them!

 

Thanks. HLVP gun...regulated down to 10 psi. Virtually no over spray.

 

OK. I'm not a painter. My first attempt on a frame came out really well. My second attempt on the sleeper was a friggin disaster. More runs than there are Rocky Mtns.

 

Well that was my first attempt since I was 15 yrs old. Back then it was acrylic lacquer sprayed with a siphon gun wet sanded and clear coated. This single stage urethayne stuff is wayyyyy easier.

 

Hey rank, I haven't read the entire post so please forgive if I missed something or cover ground already explained. When you pull the horns off the top it's super important to fill all the holes really well before paint. I stripped my whole 359 and required a good amount of work to my roof. I ended up having to re-panel two of the three section cab roof. As for train horns the 359 is set up perfect for them, place them under the bunk facing the ground. They will Rock your socks, you gotta be cool with them tho. I've blown out a few side windows on some four wheelers with this set-up. By facing them down you vibrate the ground and the sound bounces off the ground amplifying the affects. Also be sure to run a 1/2 in. air line or larger to turn some heads. I went with 5/8, the only down side to that large is if you leave the line open you will suck some major air out the tanks. Dynamat was what I used, it is good, personally I think there's better stuff out there now. When I restored the truck dynamat was probably the best at the time. Good luck with your paint job, it's a tough job took me 4 weeks to do my whole truck. Crazy amount of labor.
