Thanks for reaching out to us, Dale!
Thanks for the part number you provided! Unfortunately, 43357 isn’t pulling anything up on mine or Dexter’s end. Do you happen to see any other markings or numbers stamped on the hub itself? We can usually cross-reference those to track down the right Dexter replacement part.
Comment and let me know. Let’s see what we can dig up!
