Inside surround of sliding door window.

I have a 2005 trident and the cream plastic facia that covers the housing for the sliding door window blind has broken.
It is the outer housing that screws onto the wooden blocks beneath.
It is in two places and seems unrepairable.
Anybody knowledge of a spare anywhere prior to me contacting auto sleeper.
Regards
Andy.

I think your only option is to contact the parts dept at A/S. These are specially made for A/S to their design. I'm not sure who the manufacturer is (it could be Cheltenham laminates). Even if you could bypass A/S I'm not sure You would be able to purchase direct from the supplier. The A/S parts dept provides an excellent service and by using them directly you are helping to ensure continued availability of parts for older designs. Those design of those mouldings for the T5 only changed in the final run out models.

Many thanks for that.
