THULE G2 Blocker Side Panel Attachment fittings

[warny15]

Hi all, I have just bought my second California. I have a Thule Wind Blocker G2 side panel but unfortunately I left the fittings for the panel tension rod on my old California ! Does anybody know where I can purchase only the fittings, or even have 3D models so I could 3d print replacements ?. Many thanks
