========= update ========== this whole post was me misunderstanding the issue. Please feel free to skip.
I am sitting in my chair with my favorite beverage, and I had an epiphany. Maybe. Let me know if this will work.
Normally this is mounted with the green arrow facing the front of the goblin, and the black cables going back. In this orientation, cable 2 attaches on the right side of the shifter. If you able to reassemble this shifter with the cables facing the opposite direction, then it should work for the F40.
If you flip the shifter arm 1, and make 2 plates (green rectangle) to move the cable attach point, then mount the shifter so the green arrow points forward in your goblin, and the cables go backwards. Now cable 2 is on the left side, which should be correct for the F40.
===== Update =======
Dang, it won't work. I just sat in my goblin, and realized my mistake. When you turn the shifter around, it still moves cable 2 in the same way.
New plan. Don't turn the shifter around. Just modify the arm that cable 2 attaches to.
Behind the green circle is a pivot point for the arm that cable 2 attaches to.
If that pivot point could be moved back to where the yellow circle is, and arm 2 flipped so it goes to the yellow circle instead of the green circle, then cable 2 would move in the opposite direction. You would still need to make 2 plates like the green rectangle above, to mount the cable.
