3-Point Hitch lost a peice to the shift lever for the 3 point hitch

[DAN LANG]

I lost "something" that connects the handle of the 3 point hitch to the second lever that's moves it up and down...I can operate the 3 point hitch by pushing on this lever under the seat....but the handles is useless..cause a piece is missing...looks like its only and 1nch or two long....where can I find a diagram for the part for this ??
