I dont know  for sure  as we ourselves  didnt try  but  acording to my cousin   they tried  all the agco dealers  locally  and  the  NAPA and Carquests   and  no luck...      

I am sure your right about putting  a screw in it--- this  plate broke and  was  popping and cracking  and firing off  time - so  bad   it had to be replaced...     we found that  used  plate and it runs now... 

That particular tractors been around all the  &quot;oliver&quot;  neighbors  homes...  its not had a good reputation  since I've known of it.
