You can use the speedo cable from the Mk1/Mk1. in your Mk2. They are completely interchangeable. The Mk2 cable is a 2 part affair and the Mk1/MK1a is one part. The speedo gear will not know the difference. I have an earlier cable on my Mk2 (#463) and have installed them on every Mk2 that has left my shop. They work just fine.
