    horns no longer work on my B model and was wanting to remove them anyway, for a cleaner look. There two 10mm head bolts that hold them to the top of the cab, from the outside. Assuming the whole headliner has to come down, are there any hidden screws that hold the headliner up? Don’t want to tear the HL up, to do the job.

    Should be nutserts on the inside that "should" allow you to turn just the bolt.

    The air supply line will have to be unthreaded from the bottom of the horn. I tried lifting it from on top of the cab but it wouldn’t lift high enough to unthread it. Lines will also have to be plugged. Thought there might be some screws under certain buttons on the HL.

    Some of the old ones you must pull the door seals from top side and find screws that hold headliner in and will be a bear to get out?

    The air line. Pull it up as far as possible and cut it off. Then pull the air line down through the window post or fish it out of the dash from behind the left gauge panel. Worse comes to worse you will need to drop the headliner.

    My 99 w900l has about 8 screws. Once you take the trim down, you can pull a little down on the edges and you can feel the buttons that are solid. The buttons will snap off and hide the screws. My girl friend helped hold it up when you get to the last few screws.. good luck.

    I removed my horns on my '93 and added 4 more clearance lights. Actually put 9 new led lights on it. I ran the air lines from the horn valve back down the window post and rearward to my train horns mounted on the inside of frame and turned down. Works great for me. Have the post and lever valve in a 379 and I get seatbelts hooked on it pretty often. Yes the buttons pop off in several places in headliner and conceal screws. Pretty easy job.

    I’ve got lots of buttons any ideas on which one are THE ones that are hiding the screws?
