Default Re: Horn for a 39 1 ton truck.

The Greenbook shows different part numbers for the horn on my 40 Tonner and the horn on your 39 Tonner. It does show the same part number 51A-13823 for the Commercial (1/2 ton) and Truck (3/4 ton up) from 38-39 which suggests that its possible that the same horn used on a 39 pickup would be correct for your Tonner. If you could locate someone with a 39 pickup and take a look at their horn it might give you some idea of what you’re looking for. Good luck with the search. Also welcome to the Barn! Any photos of your truck?
