Indigo 2 broken keys need replacing

[iamtooslick]

My indigo 2 has some broken keys that need replacing. I am looking on Syntaur.com at the replacements but the Indigo 2 keys are not there. The Indigo 1 keys don't have the slot near the spring.

The TI Polar keys look the closest to the broken keys I removed.

Does anyone know if they are compatible with my Indigo 2?

Thanks.
