Looks like Aftermarket Express also cancelled the order.
“We are sorry to inform you that the part #AM117590 PULLEY, JACKSHEAVE, WELDED is no longer available from John Deere. I checked to see if it was available in the aftermarket and it does not appear to be available there either. A refund of your purchase was made though PayPal”
Not a good sign - guess there is now a limited supply of these.
