I agree with Pat. I sent my AAZ 016 to GTA in late 2015. In less than two weeks they rebuilt the trans, new 3.22 ring and pinion, new .072 fifth gear and a Wavetrac LSD. The revised gearbox transformed my CAV and greatly improved both the drivability and the top speed. The best part is that no mods were necessary to re-install the trans. I know it was difficult to find someone that could work on the 016, but I'm sure there's someone in Europe who can do it.
