Zack,
The PC1698 for the 317 tractor has a section 22 that lists all the parts for the Onan conversion.
It shows a driveshaft adapter with a part number of HE190-0684 which is NLA from Deere (try it as a 190-0684 from Cummins/Onan, but I don't know if they would still have it either.) The existence of the adapter is strong evidence that the rest of the driveshaft can be reused for the most part...
