1967 Barracuda. Horns

Contrary to my previous comment here are the two side by side. Didn’t realize I had a pair of Spartans till I went to paint them for a recent project

As you can see the Spartan is labeled on the rim, the Prestolite is labeled on the horn near the opening.

The Prestolite has a bolt on bracket, the Spartan, welded.
