SL2 throttle lever

[stevo42]

Greetings,

I have a Lister SL2 driving my 5KW, ST generator. The part that goes down the center of the throttle lever and meshes into the notches in the arc is buggered. I have had a jury rig set up for years and think it's about time to look into replacing the part if I can find one.  Anyone have one? My other option is to take it to a machine shop. Looks like it's only held on with a couple bolts "underneath" and the linkage.  Thanks in advance, Steve
