ISOFIX top tether trim missing

[rowbotx]

I’ve been searching for the trim for the ISOFIX top tether which goes in the back of the seat. It’s for the T6 Transporter, one is missing. I can find the trim for the bits that go between the back and seat on the front of the seats, and there’s loads for other vehicles but can’t find any for the VW Traspoter! Does anyone have any ideas? TIA
