Hi, have a look at one of DaveW's posts. It is titled Mr Bumble Improvements -Phase 3,
dated 09/10/13 04.38pm, there you will see a picture of the rear of a Smiths tachometer,
It is from a newer car, however it may well be the same as your tacko. [/quote]
Thank you very much!

Tomorrow I´ll have a look - or should I say I´ll try to feel behind the dash?
This forum is fantastic!!
But how did you remeber this post?
