I got mine off ebay. Yeh £12 must be for both halves.Where did you get yours from t3yls
Ive looked on shop4parts but cant work out their pricing , is it for just one half or both
eurocarparts have some for £12.36 . Is this about right for both halves
There is a how-to on here somewhere, with pics. I think they're awkward to get to but easy to fit.
