Trying to find 4-pin SPDIF bracket/header (coax out)

[donerb]

I have an ECS K8M800-M2 motherboard and am having the damnedest time tracking down a compatible 4-pin SPDIF coax-out bracket.

My first purchase was a 3-pin (didn't give specs, so for $2 I took my chances). Doesn't help much, obviously.

The wire config on the mobo is:
Pin Signal Name Function
1 SPDIF SPDIF Digital output
2 +5VA 5V analog power
3 Key No pin
4 Gnd Ground

No accessories available directly from ECS. Does anyone know of a compatible bracket header that will work with this setup?

Maybe something like this?
Appears to give a choice of coax/toslink, with 2 different 4-pin connectors.

Thanks,
DRB
