Oh yeah, I missed this point:
The MGB 5-main engine does not have a mechanical tachometer drive. So
you need an electric tach. And, to keep appearances in order, You want
to obtain the electric tach from the same model MGB as the aforementioned
flywheel, 1965-1967. Follow the wiring diagram for the MGB when
installing this tach. If you have converted your MGA from positive earth
to negative earth, this tach can also be converted from positive earth to
negative earth, just ask. But don't ask me, I have one but haven't
needed to use it yet.
