Finally broke the shaft on my wobble box yoke, and have been unable to find another.  John Deere makes a near replica in their AE38050 or AE57735, but slightly too large for my box.  Any suggestions on where to find one, or what other machines may have used a yoke this size?  Too expensive to weld, and probably won't hold anyway.

Pretty sure the forage choppers used that gear box also. Have you went on the Agco visitor webpage to see if they still carry it? A good machine shop can make a new shaft. Parts are becoming hard to get for sure. Our 390 kept breaking the mounting bolts holding the wobble box. My brother placed a thin rubber washer between the wobble box and the mounting bracket. Solved the breaking bolts issue. Vibration is the cause.

My bro had a 390 and somebody before him fabbed a green one off of a John Deere 800 swather on there, it seemed to work fine for him.
