Where can I get the g27 shifter internal parts?

[donghe08]

I figured out the problem with the G27's shifter not recognizing the gears and took my shifter apart, but then I broke it without realizing the part in the picture, so now I'm stuck with the black plastic and green plastic parts again. I did a lot of googling to get these parts but couldn't find them, so if anyone knows of a place to get them, please comment!
