thanks - I was assuming that it would be enough to fit one with the right part number. there are quite a few around for 230ks and 200s with a range of part numbers on, seen a few that match mine. Trouble with getting a 'full set' for a 320 is availability I'm on the hunt for a 320 that's maybe an MOT failure that i can get cheap and use for spares... there's a few other bits and bobs i need - including a new speaker grille after and incident at the weekend when working on this issue! (i860 may have heard me swear!) ?
