Questions
I am looking for the right front axle assembly for my Farm King 990. The original book calls out part number 10717 but I am unable to find any parts look up that references that number to a newer part. In the 1979 model year that part changed to 13578. It continued with that number through the end of production in 1984. I have no information to indicate whether is it a new number for the same part, or a different part.Reference
