I seem to remember reading somewhere that the mech was from a Citroën? Anyway, in reality the mechanism isn't hi tech so you could likely fit a unit from a junkyard with a bit of imaginative bracketry and wiring. Main thing to look for is the interface between the mech and the runner at the bottom of the glass and the distance between these interface sliders and the central pivot of the main levers. With the Pantera it's likely to be more suited to the mech from a rear door of a sedan etc, which is a bonus because these tend to get very little use.
