[Closed] SRAM trigger experts - help please!

Noticed my XX RH shifter was playing up yesterday - no click/index on downshifts, so it was a case of stab the lever and hope.

I had it to pieces this morning, and the hooky end bit of a tiny spring has snapped off, which seems to provide the tension "click" for the downshift ratchet.

I'm guessing that there's not a hope in hell of SRAM selling spare parts like that? Any body got any instructions for reassembly? I've got a pretty good idea how it works, but instructions would make life faster. (google is not being my friend here!)

Thanks!
