Once again, I am seeking the wisdom of the Early S community with regard to originality.

There's an interesting post in "WTB" (https://www.early911sregistry.org/fo...r-335-HZ/page2) seeking a passenger side horn for a '68. The WTB ad posts a page from PET showing a round horn as the one being sought, plus an underside photo showing a snail horn on the driver side and a round horn on the passenger side.

Until seeing that photo, it was my understanding that the '68 models came with matching snail horns on both sides (with low and high frequencies).

Can anyone provide more/better information on the types of horns delivered on the '68 models?

Thanks, as always, for educating the community.
