This is a chance to own a  Dukane 5A530 exponential horn 3 bolt, 1" throat adapter plate.  You will need this to properly mount a 1" throat driver such as a Dukane 5A540 to the 5A530 horn.  I am also including a single mounting bracket with the throat adapter.  The last photo shows an adapter on a horn.  The horn is not included in this listing. 

    Please email me with any questions.  Also, please check out my other items in my store.  Some of them are shown in the last photograph of this listing.  Thank you for looking and God bless!
