Mikeeyr - the two setups are unique to their models - Jason's is classic mounting used by both Jagg and HD (made by Jagg or other aftermarket supplier), and Eleft' is one made to fit between the wider frame rails of the Softtail (I know, wanted to do it on my Sporty, but frame tubes are too narrow) by HD (again by Jagg or other aftermarket supplier) but without the chrome cover for "stealth" black look.
