                            Neither my speedo nor tach are working well

                            heads.  Pricey replacements !   As my MGB GT
                            V8 is not really original it did not take me
                            long to find Speedhut replacements.   They
                            have a good selection and a brilliant web
                            site to "build" you own gauge.   Mine will
                            be very very close to the original but with
                            far better performance and features.  The
                            speedo is GPS driven - my oath - and has no
                            connections to the car (except for Lucas

                            that when I  fit them I will no longer go
