C 3 trans parts

Hey all, having a hard time finding a part I need. Rebuilding a C 3 for a buddy. I need the kick down lever inside the trans that goes thru the shifter shaft. I have been on every sight I can find. Can't find a core to rob either. Anybody know we're I can find one? Thanks cory

I wonder if one from an A4LD would work, since it's a derivative of the C3.
