Can anyone give me the original part#'s for the left and right horns from a 1973 240Z? Also, were these used on any other years? I'm missing my left horn and looking to replace one or both with the same type.

The Z Car CD says 26310-E4100 (high) and 26330-E4100 (low) up to 7/73.

Thanks Stephen. The horns I am looking at have the following markings on them.

MODEL-ME 12V3A 115dB DATE X10

Not sure what the ME or X10 stand for but I plan on doing some research to find out. So it looks like the horns on the 70-73 are all the same eh?

According to the cd, there was one from the beginning to 7/73, one from 8/73-8/74 and I didn't check beyond that. I recall Alan T. talking about dates that are coded that way, but I don't recall how to read them.
