I got this replacement joystick set with new joystick from mantis amusements last year and dont need them as i converted the Defender to a multi Williams. these are the parts i got at this link.
http://www.mantisamusements.com/joystick1.htmthese are real nice and have a much nicer feel then the original, gets rid of the sloppiness. this setup im selling was never installed and brand new.
also included is my original leafs from my old stick
if interested i will sell for $30 shipped
