Yah the problem with that is that most shops anymore are all CNC and they don't want to take the time to set up a machine for one piece. Not to mention the time to program it all in. We did find a pair of NIB shafts from Combine World out of Canada.
The 8560 uses a completely differant shaft than the rest of the Whites and it was changed in the 8570's, along with the transmissions. It is longer than the ones in the Whites, but the end that goes in the trans is smaller than the 9700, 9720's.
