Cheers, i had to get a new elbow as 1 of them was cracked, and that cap I was after, i just bought that aswell while I was at it.....£34 for two fittings, if i still worked at schlum I could have "acquired" them.
Ordered both today, so i'll get them by the end of the week, just need to sort my radiator switch leak and fire it up. Any goings on with the 3 door?
