Need help identifying a part - '04 convertible top

[herve_g]

Hi all,

I just purchased a used top (with glass window) to replace the one I currently have (plastic window).

The "new" roof is from a 2004 Boxster.

The white plastic clip holding the roof liner to the first bow is broken, as you can see in these pictures:





Does anyone know what the part # would be for it?

Thanks,
Hervé
