You're talking about the pedal assembly, correct? If so I believe that while it was made similar to many others, it was EB specific in physical mounting dimensions, if not geometry-wise. Same type of brakes to work, so guessing the gearing/number of clicks is the same as on any passenger car or truck of the vintage.
But the mounting face was for a perfectly flat, almost vertical firewall. Which was not that common I don't think. Then again, maybe they made the mounting pads similar so that they could use one part in multiple vehicles.
I know some have looked at least at a limited number of other vehicles and not found anything, but that does not mean that there isn't something out there. We'd need to do a part number cross-reference I imagine.
And just FYI in case you did not know, there were two distinctly different pedal assemblies for Broncos. The '66 through '75-ish was one design, and the '76-ish and '77 was another.
Perhaps it was the change to the new larger rear brakes that dictated that, or perhaps it was an internal design change to the mechanism. Don't know.
Maybe someone has found an alternate in the meantime. But if so I don't remember reading about it here.
Good luck!
