Cleaning keys after a pop spill... broke springs under pads

I've got a A1398 Mid-2012 Macbook Pro Retina.

Inevitably, I spilled a can of pop on the key pad... so no big deal, I start popping the keys off...

So I've broken the plastic springs under the F9 and F10 keys... they were so gummed up with pop, they would turn properly, so I soaked them in hot water and then tried to separate them as I had with the regular large keys, which came apart and went back together fine.

Unfortunately, I broke the springs trying to put them back together....

I can seem to find the correct part for the F-keys for the springs... just the whole keyboard assy.

Any ideas?
