I found a Delco Remy horn in my garage. Could someone tell me what it fits? It says "L Delco Remy, made in the USA". on the other side it says "9000, 12 V" with a overstamp of "057'. Across from that it has "A" with a overstamp of "3H1". Thank you in advance. Dale P.S. inside the horn I found "15 Delco Remy".
