Update. I found one place that had the appropriate DIN 6 hold flange for the front axle. Turns out JD used a standard metric flange of 100mm OD, Pilot 57mm, bolt circle 84mm, number / size of holes 6, 8mm. I only found one US driveline shop to supply this flange and the appropriate 1 3/8" 21 spline, and they are building the drive shaft now. I spoke with my local automotive trunk driveline, transmission shop and they recommend for AG stuff to call these guys. Chuck was super helpful.

I'll update once installed. I will fabricate a appropriate drive shaft protector that will protect the shaft going through the woods.
