Problem is Pete, its not just the UK ones.... US, Hong Kong and Euro shops ive tried or left e-mails with. Some parts, like the Diff Halves, just seem not to be available anywhere ive tried atm.
At least not that i can find anyway, after a couple of hours e-mailing. And i did find 2 webshops with them on the net, but as soon as they were ordered i got an e-mail back saying they were unavailable.
