I'm no expert, but from what I've researched it looks like the tail shafts and housings from the a340 transmissions are interchangeable (see the links below). I'm just starting to gather my parts to do this same swap on a a340e, and the hf2a case will mate to the tail housing of a a343f...
Looking for the knuckles out both sides, power steering box and steering linkage. Chances are I can make the trip north to pick them up, but might as well get a shipping quote to 98629. Thanks
