Hi, my car is in the garage having failed the MOT due to the rubber seal not being present.

Any idea where I can get hold of one, or part number?
I've had no luck in finding one so far and the garage has been useless.

Cheers

Hi, mine is in for an MOT and failed for the rubber seal not being present.
I can't seem to get hold of it, do you know the part number or even a photo/measurements, so. I know exactly what I'm looking for.

Thanks
