salvage New Holland 1495 mower (Lamoni)

Need a hard to come by header shaft(#5 in picture below) on a New Holland 1495 self propelled mower.
Located on upper left side of head.
Ours broke and apparently they are rare to non existent.
Any leads appreciated or if someone knows where there might be a machine sitting in the weeds.
