door window seals

Hello,

I have a clipper and the window seal on the passenger side door (the vertical one towards the front), half of it is missing and it makes an annoying whistling noise when travelling at anything above 40mph.  Its driving me nuts!!

Has anyone any idea where I can buy one of these from?  as ive tried a few places but to no avail.

Thanks in advance.

Ste

Found these on t'bay.  Does anyone know if these are what i need or are these from elsewhere??
Cheers

These are only fit for the bin, to be fair. A piccy showing whats missing and from where would really help. The link is to the scraper seals they fit against the windows and are horizontal, they go into the chrome strip than runs across the length of the door top.
