Looks to me like 911-424-051-09. Can’t say why -06 is titled as “with automatic heat” because that would be the option that had the dial knob in place of a lever in the center console. -09 has the 2 levers and switches that operates the eng. compartment blower fan.
Not sure if you already have the entire HB structure, but it looks like you just need the Lever, a longer collar bolt to couple onto the bracket (#2), then cable, etc to just add on what’s existing. If the above #-09 is the entire unit, it will still need everything to the engine. Try searching the dismantlers for the entire setup? Finding those loose parts could be iffy.
