Combines 8560 drive axle

I would think that any good machine shop could build it up and recut splines or build a complete new shaft.

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.

Didn't the 8560 use the White drive system bound to be something in a new White part or in a salvage yard

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.
