i just bought a set from them for my BK and was expecting them to be all chinese knock-off, but i cannot find a china marking anywhere, the coils are marked made in italy, and the bell crank, and bat bushing both have the williams stamp on them. i was expecting to have to use them as parts to refurb my old ones , but im impressed.
