My 73 convertible was beat up, poorly repaired, and hacked on good before I bought her, so total frame off resto. Heading down the final stretch now and it ain't been easy, something every step of the way. When I took it apart there were 2 horns bolted up near the lower valance on the frame section that is part of the bumper reinforcement. One had the factory connection plugged in while the other was spliced into the same wire going to the first horn. The AIM manual shows one horn bolted in the nose, center of hood. Neither of the horns I have, both with delco remey logos, fit as the manual shows. I don't believe either are correct. When searching for a replacement all I find are generic ones, seems the 73 is unique with he one, other years have 2, a high and low note, so any suggestions, generic, high or low note? See nothing factory replacement? No luck finding used 73 specific.
