Really? They would have to be the strangest people I have successfully not bought parts from. Excellent website, really kooky approach to customer service. I was after confirmation of which part would suit a particular series gearbox, nil result by phone, tried by email and received nothing but promises that they would address the inquiry. Eventually gave up and they claimed they'd been emailing pricing and info all along, apparently forgetting that at the same time they'd been saying "going to, going to".
Just had a good experience with Rimmer Bros if you can't find what you need locally.
