Ok, thanks. I have read that page before, and it is very helpful. But unless I'm missing something it doesn't actually tell me where the parts have been sourced from. I've seen on various posts what I think is the answer, but ideally I would like someone to tell me for sure what I need to get, so that I can start trawling ebay. And, as I understand it Nick is someone who knows more than most, but obviously I'm happy to be told by anyone who knows their stuff!
Thanks.
