Garry,
Will be interesting to see what this box does go for and if it gets delivered! It took me quite a bit of effort to get ZF to respond to anything I sent. I finally got the response I needed from one of their offices here in the US and was able to order and receive the part I needed, but it was exhausting trying to get it. Hope you do gte it soon. Will be interesting to see how the new ones stack up against the originals. My guess is with all the new manufacturing technologies the tolerances will be better and they will be a smoother running box.
George
