I ran across some information about the car, Trilacoochee Ford in Green Swamp, Florida offered what was called a High Water Kit, although the dealership didn't offer installation, it was a DYI kit. In that era crossing rivers was dangerous and the kit allowed the vehicle to cross the rivers in a safer way. HRP
Just goes to show the Florida Man meme isn't something that only goes back decades, they've been at it for at least a century!
I almost bought one of these for the total cool factor of it all. They were used to drive through a standing tobacco crop and spray. I didn’t think it would clear the wires once I had it loaded onto a trailer.
