tell me if im incorrect but it looks like what your trying to do is just see if a forward shift will work in your 99 A340F so the shifter can clear the body, correct? it looks like all you'll need to do is just find a forward shift t-case and throw it in there (allowing you to not have to cut the floor) that or mod the top shift rails turning them into forward shift rails in the last picture so you can throw on a base plate and have the shifter there. (then youd have to find another plate for the actual case) my question is about the first picture, why dont you just cut the floor back a little bit and run it like that then it would allow you to run a tranny thats 5 years newer. hopefully this doesnt sound confusing, i think ive almost confused myself.
