I've got a pair of Delco-Remy horns that I have no idea as to what they fit. They are 12V and have the following codes stamped on them. All of these codes are stamped on the bell end of the horn except for S2 and N1 which is stamped near the male spade connector. Here are the codes: 9000 12V and 295 along with what is either a G or an O followed by A4 . The other horn is stamped 9000 12V 293 and either a G or an O followed by D5 . Any help on this would be greatly appreciated!!
