These horns are GM licensed reproductions. Like the originals, these have the correct black semi-gloss finish and are all metal construction. One is the Hi-note (C) with the second being Lo-note(D). Included are mounting brackets that bolt (originals were welded) on the back of the horns which gives flexibility in mounting for different applications. No other mounting hardware or wiring is included. Sold only in pairs.
