Take it thats just a standard Z22se Rocker cover ?
I have the one that came from the Zafiras old engine if thats any good ?
Could be couriered via interparcel economy for about £8.00 plus the price of the cover itself... looked on ebay, they seem to be between £15 and £20.00 plus post, so how about £20.00 posted ?
Would take a few days and i would have to find a box, but let me know if your interested as it will go down the scrap yard wit the rest of the rubbish in the garage at the weekend otherwise
