There is also a detailed article about fitting the SPA gauge on the Morgan Three Wheeler Club website, May 2020. https://www.mtwc.co.uk/full-list-of-articles/. This was done from KBMOG's initial development fit and my own experience. Good to see you are still on the forum Keith. If you are a MTWC member you can access all the articles. If not PM me your email and I will try and sort out the info for you. The SPA installation is good but the billet plate can always be used for another gauge fit. It's handy to keep a close eye on what is happening with the oil in your expensive engine, other than just a light to tell you it's melted.
