I hav ea Trick Flow elbow on my car, and when I got it I had the stock non-vented opti, so I just threw away the grommet they give you with the elbow. I recently swapped to a vented opti and need the grommet for the opti vent line now. I've tried the local auto parts and hardware stores and I can't seem to find what I need.

Anybody keep their grommet from the TF elbow and not need it?
