Will check for you as far as the Speedo is concerned. I am sure that you would know, but a 450 Speedometer, whilst it will obviously work, will not give you a correct speed reading. Regards Styria

Styria, I'am a great believer in don't fix what isn't broken, so I will fix if and when it looks like a problem. It is nice to know where it is if I need to attend to this, thank again for your help .
