Seeking STL or Dimensions for IGT S-Plus Hopper Optic Flag (Old Style)

[Comic]

Hi everyone,
I’m in the process of repairing my Red, White, and Blue IGT S-Plus. The black plastic impact arm on my hopper optic flag (the part the coin strikes) has snapped off.
The housing and pivot pin are still in great shape, so I’m planning to 3D print a replacement flag in PETG. Before I spend a few hours in Fusion 360 modeling it from scratch, I wanted to check a couple of things with the experts here:
Does anyone have an STL file for this specific S-Plus hopper flag?
If not, does anyone have the "throw" measurements? I want to make sure the "tail" that breaks the optic beam is the correct length so I don't get "Hopper Bridge" or timeout errors.
Alternatively, if someone has a spare "old style" black flag they'd be willing to sell, please let me know!
I've attached photos of my broken part and the housing for reference.
Thanks for any help you can provide!
