salam, @janzi1, first of all the spare parts of these bikes are very difficult to find, I own the c70 1982 model also known as BAYASI in original (HM) Stanley Japanese parts, you can tell me what parts you need, I can arrange them for you but keeping in mind, these models are now Vintage models and considered as classics, so the parts are very rare and very expensive, but I would say that it's worth it, and it is a million times better than these cheap chinese bikes which are being produced nowadays
