Does anyone on here know anything about a company that made aftermarket vertical stabilizers that would have been installed in the late 90's? I have a 555c Ford with them on it. I would like to swap them out for standard ones if it isn't too difficult. They aren't the normal side shift stabilizers that Ford offered. They look like they bolt on in place of the standard stabilizers. The previous owner told me that a cemetery department owned the machine and the stabilizers were designed to fit in between existing graves. Thanks
