weather-seal gasket replacement

[joshmurrah]

My wife bought me a 16-35 II at the LensRental sale last cyber monday. I'm loving the lens, however there's several nicks in the weatherseal gasket on the back.

I'm aware that this is really easy to replace, however I have no idea where to source the gasket part itself.

Does anyone know where/how I can obtain this part?

Has to be sent to Canon if I am not mistaken. That part is integrated into the lens mount.
