Beat me to it!
As he said, all bars were either dealer or owner installed. Ford never had one, although I do seem to remember they did list one as an "option" at one point in literature. But even that would have likely been in the dealer-installed category.
Maybe the lawyers said it wasn't a good idea to make people think you could roll over in their vehicles?
But if you have just about any aftermarket bar, you can weld in a front and/or rear cage setup. From fully custom, local bent stuff, to (almost) ready to go like this stuff:

There's a minimal amount of leeway built into the slightly too long tubes, but if your bar looks too much different from what's pictured, you may need to have someone local do a custom.
Good luck.
And make sure that however it's set up, you keep in mind all the clearances needed up front. Knees, window cranks, wing-vents, dash controls, glove box doors, etc.
All of the above need to be taken into account when doing the final setup of a front cage in an EB.
