MacBook Retina Pro 2013 - Broken Right Fan ZIF socket

I recently spilled beer on my laptop (Early 2013 15' Macbook Pro Retina), resulting in some corrosion on the connection between the logic board and the top case/keyboard. I soaked it in iso alcohol and removed the corrosion with a fine brush. After putting it together, it works fine (as far as I can tell)!

Unfortunately, when re-assembling the laptop, I broke the retaining flap on the right fan ZIF socket. For reference, it's the socket shown here:

The socket is still intact, and the cable fits in it, but I think without the plastic latch/flap the cable won't engage. I put some electrical tape under the cable to hold it parallel but that doesn't help it engage with the socket.

I ran the apple hardware diagnostic tool (startup while holding the 'D' key) and it gave me this error - 4MOT/4/40000002 - Right-Side-0. It seems like the laptop can't recognize the right fan without the socket being locked down.

Is there any way to fix just the flap? Or the ZIF socket? I have some experience doing SMD soldering so it's not out of the realm of possibility to replace the socket itself if I can find the part.
