Should be Husqvarna part number 583301401, if I’ve done my research correctly. I dd not cross it over to Dana or Peerless numbers, but a good repair shop should be able to do that for you.
Don't waste yer time looking for another Dana. They had to quit making parts before my warranty ran out on a 42" rider.
It's a POS. 1st thing is leaking at the wheels..
