New here. First post, although I've been lurking for a while. I'm not sure if they're the same or compatible but I just converted a '76 Raleigh record to a single speed and still have all the components for the front and rear derailers. They're the original hurets that came on it. I'd sell them to the shop for $160-$180. Quite a bit less for you if you to buy them yourself (mostly shipping and a little beer money). But the bike shop needs to pay for their mistake. And I'll overcharge them like they do us.
