Larry,
Believe what you will. As the UK spec 1500
I have a 73 Spitfire and I'm thinking about putting a
cd player in it. Has anyone on the list done this and
what changes had to be made? Did it slide right in
the existing hole or did you have to do any cutting?
I read that someone who put in a powerful stereo
system replaced the alternator with

Surprisingly (or not) my 1976 original electronic tach is pretty
accurate. Maybe just lucky.
I have compared to external tachs (including various government ones at
emissions testing, a test unit I have, etc. ) and always been spot on as
far as I can tell.

Ant the competition manual was written even before then.
Surely someone has improved electronic tachometers since then. That's
my point.

That manual was written when? Quite possibly that statement may not
hold up anymore.

How is this true? It seems to me that a gearbox out of a GT6
would be assuming a different final driveratio and therefore a
