RW, Air horn valve and bracket location.

[jackdk]

Do any R, RW, DM, etc members have their headliner pulled done to get me pictures of the location of the airhorn valve, bracket and location? The previous owner removed the lights, horns, and roof vent from on top of the roof. I partially pulled down my headliner to day, and I can not figure out where it would even go. Has to be near the grommet in the headliner in assume, but I can not find anything that looks like the original location

Pictures or factory diagrams would be fantastic. If there are part numbers (valve, bracket, lanyard etc) for any of the items, that would be a BIG help as well. 

Thanks in advance, for any help, picture, or part #s.

Unfortunately I just put mine back together I had the roof stripped for paint. Hopefully someone will be along shortly to help. It's always a tough job putting together something you didn't take apart

R688 of 1988. Rectangular Hadley air horns. That's the way I saw it when we took the headliner off prepping the cab for restoration. Your setup should be the same. Or definitely could be done this way even if it was different from the factory. Browsing flea bay listings I saw "Mack air horn valve" items and those looked similar to what I had in the truck. The part didn't seem unique to Mack and used by other truck makers.

OH MY! BROVO Vladislav. That is absolutely perfect. If its not to late, do you have a closeup picture of the horn valve and bracket. I have a feeling the previous owner took out the bracket

Unfortunately it's not of the same easyness as the pics above. Otherwise I wouldn't hide a rabbit in a hat. We de-dressed the cab for body works a couple years back and I made pics for re-assembly reference. Didn't photo the valve and brackets since didn't put my hands particulary on them (so far). We just put marks on them and packed in some cardboard box together with other stuff.

OK, no problem, and I do appreciate what you already sent. Thanks again.

That's quite the puzzle you've got there with the missing air horn valve and bracket. I can only imagine how bewildering it must be to try and figure out where everything originally went. Although I don't have personal experience with the R, RW, DM models, I think I can still offer some valuable insight. I recently came across a Dewalt Train Horn on BossHorn that offers a comprehensive set, including a valve, bracket, and all the necessary parts for installation. The product details and instructions could give you a pretty solid idea of what you might need and where it might go in relation to your own vehicle's setup.
