I'm looking to source a replacement for a specific clutch disc. The part has some unique markings, along with a diameter of around 16cm. It's crucial that the new disc matches the specifications closely to ensure proper functionality in the system where it will be used. Could you provide details on availability, pricing, and lead time for this part? Additionally, if you have any recommendations on compatible alternatives, I'd love to hear them. Looking forward to your prompt response so we can move forward with this order. Thanks!
